[Problem to be solved by the invention] 

According to the slider described in Patent Document 1, since the height position of the upper end of the pressing part that presses and fixes the stop claw body is on the same plane as the upper surface of the upper wing plate, or is lower than the upper surface, even if the slider is pulled The pull tab will not collide with the pressing part, and it can also prevent the pressing part from contacting other components, thereby preventing the pressing part from being damaged by direct external force when the slider is in use. extrusion deformation. Therefore, the following effects can be achieved: when the other end of the stop claw is fixed by the pressing portion, the set gap size can be stably maintained, and the movement of the stop claw is not easily restricted when the slider is used. the

However, when the stop pawl is inserted into the insertion groove, there is a possibility that the stop pawl is not arranged in the center of the insertion groove in the width direction, but is shifted to either side of the left and right, so that it is placed in a state of contact or extremely close to the press. An inner side of the tight part. In this case, in the conventional slider as described in Patent Document 1, if the opposing pressing parts are bent to the inside in order to press and fix the stopping pawls, the stop will stop from the initial stage of bending. The pressing part on the side where the pawls contact will strongly contact the corners of the stop pawls, and therefore, the pressing part may become a curved shape that is unbalanced left and right and be pressed. As a result, an excessive load is applied to a pressing part, and cracks may be generated in the pressing part starting from the contact part with the stop pawl. the

[Example]

<Example 1>

Fig. 1 is a perspective view showing a state in which components constituting a slider for a slide fastener according to Example 1 of the present invention are separated, and Fig. 2 is a perspective view showing a state in which the slider is assembled. 3 is a central cross-sectional view of the semi-finished product before the pressing operation of the slider according to Embodiment 1 of the present invention, when a cut surface is formed parallel to the front-rear direction and the up-down direction, and shows before (a) and after the stop pawl is placed In the case of (b). the

Slider 1A for slide fasteners of Example 1 includes: slider main body 2 ; handle 5 held by slider main body 2 so that one end is rotatable; In the slider 1A of Example 1, the slider main body 2 and the handle 5 are manufactured by die-casting using metal materials, such as a copper alloy, an aluminum alloy, and a zinc alloy. Furthermore, the stop pawl 6 is produced by press forming using a metal material such as stainless steel or copper alloy. the

The slider body 2 includes: an upper wing 21 , a lower wing 22 , and a connecting column 23 connecting the front ends of the upper and lower wings 21 , 22 . On the left and right sides of the upper blade 21 , upper flanges 24 are formed toward the lower blade 22 , and on the left and right sides of the lower blade 22 , lower flanges 25 are formed toward the upper blade 21 . the

Moreover, the slider main body 2 includes: an introduction port 26, which is the front end of the slider main body 2, and is arranged on the left and right sides of the connecting column 23; and an engaging opening 27, which is arranged at the rear end of the slider main body 2; Between 21 and 22, a Y-shaped element guide path 28 connecting the right and left inlets 26 and the meshing inlets 27 is formed. the

The upper wing plate 21 of the slider main body 2 includes: an insertion groove 32, which is extended in the front-rear direction, and the stop claw body 6 is inserted therein; The recess 33 is set at the front end of the upper wing plate 21 to sandwich the insertion groove 32 from left to right, and is recessed in a manner lower than the upper surface of the upper wing plate; a pair of pressing columns 34 is used to sandwich the insertion groove 32 from left to right The way is erected from the bottom surface of the concave portion 33; the raised portion 35 is arranged between the pull piece holding portion 31 and the concave portion 33 and is inserted into the left and right sides of the groove 32, and is raised from the upper surface of the upper wing plate 21; and the pull piece The detachable part 36 engages so that the handle 5 can be detached when the handle 5 is laid down on the side of the engaging opening 27 . Furthermore, the side wall 39 and the pressing column 34 are symmetrical on the left and right sides with the left and right centerline of the slider main body 2 as the axis. the

The handle holder 31 includes a pair of front and rear handle pressing protrusions 31a, 31b protruding from the left and right sides of the insertion groove 32, and inserts the following connecting rod 53 of the handle 5 into the front and rear handles. After pressing between the protrusions 31a, 31b, the front and rear pair of handle pressing protrusions 31a, 31b are bent in a direction to approach each other and pressed, whereby the connecting rod 53 of the handle 5 can be held rotatably. In the pull tab holding part 31. the

The insertion groove 32 has a groove width equal to or slightly larger than the width dimension (dimension in the left-right direction) of the stop claw body 6 so that the stop claw body 6 can be stably inserted. Further, at the rear of the insertion groove 32 , when the stop claw body 6 is inserted into the insertion groove 32 , a claw hole 37 of a claw portion 61 described below of the stop claw body 6 is pierced so as to be able to be inserted therethrough. the

The recessed portion 33 is recessed on the upper surface side of the portion of the upper blade 21 to which the connecting column 23 is connected (that is, the front end portion). In Example 1, since the insertion groove 32 is extended in the front-rear direction at the center portion of the recess 33 in the left-right direction, the recess 33 is spaced apart from the left to the right so as to sandwich the insertion groove 32 . Furthermore, a stepped portion 38 having a stepped surface at a height position between the upper surface of the upper blade 21 and the bottom surface of the recessed portion 33 is formed in a portion surrounding the front half of the recessed portion 33 . the

The stop claw body 6 is made of metal such as copper alloy, or stainless steel or copper alloy, and has elasticity, and includes a claw hole 37 at one end of the slider main body 2, which can be inserted into and pulled out from the sprocket guide path 28. The claw portion 61 and the other end include a hook portion 62 inserted into the front end 32 a of the insertion groove 32 . The hook portion 62 is formed by bending the other end to the insertion groove 32 side. The front end 32 a of the insertion groove 32 is formed as a concave portion inclined downward, and the hook portion 62 can be fitted there. the

Between the claw portion 61 and the hook portion 62 of the stop claw body 6, a cover portion 63 having a substantially U-shaped cross-sectional view is provided close to the claw portion 61, and the cover portion 63 is a connecting rod that covers the handle 5 from above. 53 and the cam portion 56 , and a flat portion 65 placed along the insertion groove 32 is provided close to the hook portion 62 . the

In slide fastener slider 1A of Example 1, the width of the insertion groove 32 in the left-right direction, that is, the distance from one side wall 39 to the other side wall 39 of the insertion groove 32 is constant. Please refer to the partial cross-sectional view of the AA' line in Figure 3(b), that is, Figure 4-1, the partial cross-sectional view of the BB' line in Figure 3(b), that is, Figure 4-2, and the partial cross-sectional view of the CC' line in Figure 3(b). 4-3. For example, if the width of the insertion groove 32 in the portion sandwiched by the protruding portion 35, the portion sandwiched by the pressing column 34, and the front end 32a of the insertion groove is respectively d _A , d _B , and d _C , then d _A =d _B =d _C . At this time, the movement of the stop claw body 6 inserted into the insertion groove 32 toward the left and right direction is restricted by the side wall 39 of the insertion groove 32, so the movable distance of the stop claw body 6 towards the left and right direction is equal to the width of the insertion groove 32, Therefore, it cannot be offset to the left or right beyond this width.

On the other hand, as can be seen from FIG. 4-2 , the left and right inner surfaces 41 of a pair of pressing columns 34 erected in such a way as to sandwich the insertion groove 32 from the left and right are more present than the left and right side walls 39 of the insertion groove 32 . Left and right outside. From another point of view, there is a step difference between the left and right side walls 39 of the insertion groove 32 and the left and right inner surfaces 41 of the pair of pressing columns 34 . Furthermore, the distance (D ₁ ) between the left and right inner surfaces 41 of the pair of pressing posts 34 is greater than the width (d _B ) of the insertion groove 32 .

Therefore, in order to be in the state (semi-finished product of slider) of Fig. 5 (a) before being in the state (semi-finished product of slide member) before being in the clamping column 34 clamping and fixing the stop claw body 6, the stop claw body 6 is pressed and fixed so that the left and right clamping columns When 34 is bent to the inner side, it can be avoided that the pressing post 34 contacts the corners of the stop pawl 6 at the initial stage of bending. In addition, the pressing posts 34 are bent to a certain extent and contact the stop pawls 6 from above so as to be pressed against each other. Therefore, fluctuations in the contact positions between the left and right pressing posts 34 and the stop pawls 6 can be suppressed. Therefore, it is less likely to cause a pressing failure than conventionally. the

Fig. 5(b) is a diagram showing the state of the pressing rod 34 at the end of the pressing operation. At this time, the left and right inner surfaces 41 of the bases of the pair of pressing columns 34 exist on the left and right outer sides than the left and right side walls 39 of the insertion groove 32 . Furthermore, it can be seen that the distance (D ₂ ) between the inner surfaces of the bases of the pair of pressing columns 34 is greater than the movement distance (d _B ) toward the left and right of the stop pawl 6 inserted into the insertion groove 32 .

In addition, in the present invention, the pressing column 34 is a part that is plastically deformed by the pressing operation of the stop claw body 6, and the base of the so-called pressing column 34 refers to the part of the stop claw body 6 that is plastically deformed due to the pressing operation. However, as described in this embodiment, when there is a clear boundary between the insertion groove 32 and the pressing column 34 due to the step, it refers to the part where the distance between the opposing side surfaces is enlarged due to the step. . the

The raised portions 35 are arranged on the left and right sides of the insertion groove 32 so as to protrude from the upper surface of the upper blade 21 . If such a bulge 35 is arranged, then, for example, when the stop claw body 6 is arranged in the insertion groove 32, and then the stop claw body 6 is moved up and down in the insertion groove 32 by the operation of the handle 5, even the stop claw body A part of the body 6 moves to the top compared with the upper surface of the upper wing plate 21, and the stop claw body 6 can be hidden from the left and right sides through the bulge 35 so as to prevent the stop claw body 6 from breaking free from the insertion groove 32. Thereby, the appearance of slider 1A can be improved. the

And this raised part 35 limits the rotation limit of the handle 5 by abutting on the handle 5 when the handle 5 is attached to the slider main body 2, and it falls on the connection column 23 side as follows. Thereby, even if the handle 5 is completely laid down on the connecting column 23 side, a gap can be provided between the dropped handle 5 and the upper surface of the upper blade 21 , and the handle 5 can be prevented from colliding with the pressing column 34 . the

The pull-tab detachable part 36 protrudes upward from the center of the upper surface of the end part of the upper wing plate 21 on the side of the engaging opening 27 . The pull tab detachment part 36 includes: a neck 36a standing up from the upper surface of the upper wing plate 21; and a detachment head 36b disposed on the upper end of the neck 36a and swollen toward the left and right direction compared with the neck 36a . In this case, the dimension of the front-back direction of the detachable head part 36b is set to the same dimension as the neck part 36a. Furthermore, the upper surface of the detachable head portion 36b is formed flat, and the left and right side edges are formed outwardly in an arc-shaped expansion. the

The handle 5 of Example 1 includes: a handle main body 51; left and right arm parts 52 extending in parallel from one end of the handle main body 51; and a connecting rod 53 connecting the front ends of the left and right arm parts 52. . And the central part of the handle 5 is provided with the rectangular opening window part 54 which penetrates in the front-back direction, and arrange|positions at the other end side of the handle 5 from the side wall part surrounding this opening window part 54. On the side wall portion 54a, left and right cantilever locking pieces 55 are extended toward the connecting rod 53 side. the

In particular, the left and right cantilever locking pieces 55 include: first locking piece portions 55a extending obliquely from the base end side toward the front end side at a distance from each other; and extending parallel to each other from the front ends of the first locking piece portions 55a The second locking piece portion 55b. In this case, the distance between the left and right second locking pieces 55b is set to be larger than the width dimension of the neck portion 36a of the handle detachable portion 36 disposed on the slider body 2 and smaller than the handle detachable portion 36. The width dimension of the snap-off head 36b. the

Near the center in the longitudinal direction of the left and right cantilever locking pieces 55 , anti-coupling protrusions 57 are protrudingly provided on the inner surfaces of each in a direction approaching each other. When producing sliders industrially, there are steps such as a coloring step performed in batches for many sliders. In this case, since a large number of sliders are handled in a mixed state, both sliders may be connected when the handle 5 of another slider enters the opening window part 54 of a certain slider. Linked slides must be pulled back from each other, but doing this is unproductive and is desirable to avoid. Therefore, the occurrence of this problem can be prevented by the existence of the above-mentioned connection prevention protrusion 57, and the production efficiency can be improved. the

The connecting rod 53 of the pull tab 5 is formed in an elliptical column shape with an elliptical cross-section, and a cam portion 56 is integrally provided at the central portion of the connecting rod 53, and the cam portion 56 protrudes from the connecting rod 53, The left and right arm parts 52 and the opening formed by the one end edge of the handle main body part 51 are inside. This cam part 56 is a cross section of the cam part 56 perpendicular|vertical to the longitudinal direction of the handle 5 exhibits the taper shape which decreases gradually from the base end side of the cam part 56 toward the front end side. the

The cover portion 63 of the stop pawl 6 has a width dimension smaller than the interval between the left and right handle holding portions 31 arranged on the slider body 2 and larger than the groove width of the insertion groove 32 formed in the slider body 2 . Furthermore, the portion of the stop pawl 6 on the other end side from the cover portion 63 has a width equal to or smaller than the groove width of the insertion groove 32 formed in the slider main body 2 . the

Moreover, the slider 1A of the first embodiment is, for example, as shown in FIG. The portion 56 faces a direction substantially parallel to the upper surface of the upper blade 21 . Now, the cam portion 56 of the handle 5 does not interfere with the cover portion 63 of the stop claw body 6, so the cover portion 63 of the stop claw body 6 is not pushed up by the cam portion 56, and becomes the claw portion 61 of the stop claw body 6. A state protruding into the element guide path 28 via the claw hole 37 . the

Therefore, when the slider 1A of Embodiment 1 is inserted through the chain element row to form a slide fastener, the handle 5 can be made to fall on the meshing opening 27 side of the slider main body 2, so that the claw portion of the stop claw body 6 61 protrudes into the sprocket guide path 28 , is snapped into the sprocket row, and maintains the stop position of the slider 1A relative to the sprocket row. the

Furthermore, when the handle 5 is made to fall on the meshing opening 27 side of the slider main body 2 in this way, it can arrange|position by pushing the handle 5 toward the handle detachment part 36 arrange|positioned at the slider main body 2. The cantilever locking pieces 55 on the left and right of the handle 5 go over the detachable head portion 36b of the handle detachable part 36 while being bent outward, and are engaged with the handle detachable part 36 of the slider main body 2 . the

In this manner, the handle 5 can be held in a fallen state by engaging the cantilever locking piece 55 of the handle 5 with the handle detachable part 36 of the slider main body 2 . Therefore, the state in which the claw part 61 of the stop claw body 6 protrudes into the element guide path 28 and is engaged with the element row can be stably maintained, and the slider is reliably held at this stop position. Moreover, the engaged state of the cantilever locking piece 55 of the handle 5 and the handle detachable part 36 of the slider main body 2 can be released easily by turning the handle 5 in the direction to separate from the upper blade 21 . the

Furthermore, slider 1A of Example 1 is as above-mentioned, and the cam part 56 of the handle 5 has a tapered shape. Therefore, for example, as shown in FIG. 2 , even if the cantilever locking piece 55 of the handle 5 is not engaged with the handle detachment part 36 of the slider body 2 , the handle 5 is placed on the handle detachment part 36 . , and arranged in a state inclined relative to the upper surface of the upper wing plate 21, the cam portion 56 of the handle 5 will not interfere with the cover portion 63 of the stop claw body 6, so that the claw portion 61 of the stop claw body 6 can It protrudes into the chain tooth guide path 28 and is fastened to the chain tooth row. the

Moreover, even if the handle 5 is lifted up slightly in order to, for example, release the state that the handle 5 is fastened to the pull-tab detachment 36 , as long as the cam portion 56 of the handle 5 does not interfere with the cover portion of the stop pawl 6 If the handle 5 is rotated within the range of 63, the claw portion 61 of the stop claw body 6 will not be pulled out from the sprocket guide path 28, so that the handle 5 can be released while the slider 1A is held at the stop position. buckle status. the

On the other hand, in the slider 1A of Example 1, the handle 5 is pushed up from the state where the handle 5 is lying on the side of the engagement opening 27 of the slider main body 2 so that it is directed toward the front facing the upper wing 21 . When standing upright in the intersecting direction, the handle 5 will incline more than a specific inclination angle with respect to the upper surface of the upper wing plate 21, whereby the cam portion 56 of the handle 5 interferes with the cover portion 63 of the stop claw body 6, and stops the claw body. 6 is pushed up by the cam portion 56, so that the claw portion 61 of the stop claw body 6 is pulled out from the sprocket guide path 28. the

Furthermore, the slider 1A of Example 1 makes the handle 5 fall on the side of the connecting column 23 in a self-standing state, so that the cam portion 56 of the handle 5 does not interfere with the cover portion 63 of the stop claw body 6, so that the stop claw The cover part 63 of the body 6 descends, and the claw part 61 protrudes into the chain-tooth guide path 28 to be engaged with the chain-tooth row. Thus, the slider 1A can be held at the stop position. the

Next, a method of assembling the slider 1A of Example 1 will be described. First, the slider main body 2 is prepared. In the slider body 2, the front ends of the upper wing 21 and the lower wing 22 are connected by a connecting column 23, and a Y-shaped chain tooth guide path is arranged between the upper wing 21 and the lower wing 22. 28, and the upper wing plate 21 includes: an insertion slot 32, which is used to insert a stop claw body 6 that includes a claw portion 61 at one end; left and right pull tab holders 31, which can rotate and hold one end of the pull tab 5; For the pressing column 34, it is used to press and fix the stop claw body 6, and it is erected in a manner of sandwiching the insertion groove 32 from the left and right; and the claw hole 37, which can be inserted through the claw. Section 61. The slider main body 2 can arrange the stop claw body 6 so that the claw portion 61 can move the sprocket guide path 28 through the claw hole 37 through the operation of falling down and standing up of the handle 5 . Plug in, pull out. Moreover, the left and right inner surfaces 41 of the pair of pressing columns 34 are more present than the left and right side walls 39 of the insertion groove 32 that determine the movement distance of the stop pawl 6 inserted into the insertion groove 32 in the left and right direction. on the left and right sides. the

Next, the connecting rod 53 of the handle 5 is inserted between the front and rear handle pressing protrusions 31a respectively included in the left and right handle holding parts 31 of the slider main body 2, and the handle 5 is laid down on the slider main body 2. In the state of the meshing port 27 side, the protrusion 31a for front and rear handle crimping is bent toward the direction which mutually approaches, and it crimps. Thereby, the handle 5 is hold|maintained rotatably centering on the connecting rod 53 with respect to the slider main body 2. As shown in FIG. the

Next, in the slider main body 2 holding the pull piece 5, the claw portion 61 of the stop claw body 6 is inserted into the claw hole 37 of the slider body 2, and the cover portion 63 of the stop claw body 6 covers the pull piece from above. 5, the stop pawl 6 is inserted into the insertion groove 32 of the slider main body 2. At this time, the hook portion 62 of the stop pawl 6 is fitted into the front end 32 a of the insertion groove 32 . As a result, the stop pawl 6 is arranged at a specific position on the slider body 2 . the

Thereafter, in order to fix the stop claw body 6 to the slider main body 2, the pair of pressing posts 34 are each bent inwardly to be pressed and fixed. Here, the left and right inner surfaces 41 of the pair of pressing columns 34 of the slider main body 2 determine the left and right movement distance of the stop pawl 6 inserted into the insertion groove 32 in comparison with the left and right side walls 39 of the insertion groove 32 . Therefore, in this pressing and fixing step, the inner surfaces of the pair of pressing columns 34 are in a non-contact state with the stopping pawls 6 before being bent to a specific position. Thereafter, while the inner surfaces of the pair of pressing columns 34 are brought into contact with the stop pawls 6, the stop pawls 6 are pressed downward. In this way, the pressing columns 34 can be plastically out of shape. the

By performing such operations, the slider 1A of Embodiment 1 shown in FIG. 2 is assembled. In addition, the step of pressing and fixing the handle 5 toward the handle holder 31 can also be performed after pressing and fixing the stop claw body 6 on the slider body 2, but pressing and fixing the stop claw body 6 to the slider body In the step above 2, it is necessary to hold the handle 5 separately, and therefore, it is preferable to fix the handle 5 to the handle holding part 31 in advance in terms of operability. the

<Example 2>

The slide fastener slider of Example 2 is the same as that of Example 1 except that the structure of the stop claw body 6 is different, so only the stop claw body 6 will be described. The stop pawl 6 of Embodiment 2 is, as shown in FIG. 6 , from the middle of the upper surface of the flat portion 65 toward the front, until the curved portion 66 forming the boundary between the flat portion 65 and the hook portion 62 , on the left and right sides of the upper surface. R chamfers 64 are formed at the corners. FIG. 7 schematically shows a sectional view (a) of a non-chamfered portion indicated by a dotted line E in FIG. 6 and a sectional view (b) of a chamfered portion indicated by a dotted line F. In FIG. The chamfering radius of the R chamfering portion 64 can be appropriately set in consideration of the size of the slider and the stress reduction effect, but it is preferably set in the range of t/2 to t/3 (t is the thickness of the plate thickness, see FIG. 4 ). . the

Same as embodiment 1, in order to press and fix the state of Fig. 8 (a) (semi-finished product of the slider) before the stop claw body 6 is compressed and fixed by the compression column 34, the stop claw body 6 is compressed and fixed, and When the left and right pressing posts 34 are bent inwardly, it is possible to prevent the pressing posts 34 contacting the stop claws 6 from coming into contact with the corners of the stop claws 6 at the initial stage of bending. In addition, the pressing post 34 is pressed from above after being bent to some extent, and contacts the stop pawl 6 , so that the fluctuation of the contact position between the left and right pressing posts 34 and the stop pawl 6 can be suppressed. Therefore, it is less likely to cause a pressing failure than conventionally. Furthermore, in embodiment 2, the R chamfer 64 is formed on the stop claw body 6, so as shown in Figure 8 (b), when the inner surface 41 of the pressing post 34 contacts the stop claw body 6, it can be chamfered at R. Sliding on corner 64, thereby can carry out compression smoothly. Therefore, the stopping pawl 6 is less likely to be caught by the pressing post 34 , and therefore, the stopping pawl 6 can be easily arranged at a specific position corresponding to the degree of bending of the pressing post 34 . Furthermore, since the local stress on the contact surface of the pressing pin 34 with the stop pawl 6 is reduced, cracks are less likely to be generated from the contact surface. the

Furthermore, the first R-chamfered portion 64 extends from the flat portion 65 to the upper surface of the curved portion 66 . The stop claw body 6 is made of a flat plate, but in general, it is made in the following order: the shape of the stop claw body 6 is punched out from the plate material, and the uniform and flat stop claw body 6 is contacted with the pressing column 34 The corners are subjected to R-chamfering processing and then bending processing to form the hook portion 62 or the cover portion 63 . At this time, the R-chamfered portion is formed over the plastically deformed portion of the bent portion 66 , whereby the R-chamfered portion can be stably formed when bending processing is performed to form the hook portion 62 . the

<Example 3>

Since the slider for slide fasteners of Example 3 is the same as Example 1 except the structure of the slider main body 2 being different, only the slider main body 2 is demonstrated. FIG. 9 is a perspective view showing the structure of the slider main body 2 of the slider according to the third embodiment. Since the basic structure is the same as that of Example 1, it will not be described repeatedly. The major difference between the slider body 2 used in the slider of the second embodiment and the slider body of the first embodiment is the relationship between the insertion groove 32 and the pressing post 34 . the

In the slider for a slide fastener of Example 3, the width|variety of the left-right direction of the insertion groove 32 differs by a part. Fig. 10-1 is a diagram corresponding to the AA' line sectional view of Fig. 3 in the slider of Example 3 of the present invention, and Fig. 10-2 is a diagram corresponding to the BB' line of Fig. 3 in the slider of Example 3 of the present invention As for the cross-sectional view, Fig. 10-3 is a cross-sectional view corresponding to line CC' of Fig. 3 in the slider according to Embodiment 3 of the present invention. If the width of the insertion groove 32 of the portion sandwiched by the protruding portion 35, the portion sandwiched by the pressing column 34, and the front end 32a of the insertion groove is d _A' , d _B' , and d _C' respectively, then d _{A '} =d _C' <d _B' . Therefore, the portion where the width in the left-right direction of the insertion groove 32 is the shortest is sandwiched by the raised portion 35 and the front end 32a of the insertion groove.

At this time, the movement of the stop claw body 6 inserted into the insertion groove 32 toward the left-right direction is restricted by the shortest part of the insertion groove 32 , so the movement distance of the stop claw body 6 toward the left-right direction is separated by the raised portion 35 . The width (d _A' = d _C' ) of the insertion groove 32 at the front end 32a of the insertion groove is equal to that of the insertion groove, so that it cannot deviate to the left or right beyond this width. On the other hand, the left and right inner surfaces 41 of the pair of pressing posts 34 determine the moving distance of the stop claw body 6 inserted into the insertion groove 32 toward the left and right direction in the left and right side walls 39 of the insertion groove 32 (here The portion sandwiched by the protruding portion 35 and the front end 32a) of the insertion groove are further present on the left and right outer sides, respectively. Moreover, the distance D _{1 ′} between the left and right pressing columns 34 is longer than the movement distance of the stop pawl 6 in the left and right direction (d _A′ =d _C′ ).

Therefore, as can be seen from FIG. 10-2, each inner surface 41 of the compression column 34 and the side wall 39 of the insertion groove 32 existing on the lower side of the compression column 34 are respectively located on the same plane. The distance _D1 between the tightening posts 34 is equal to the width d _B' of the insertion groove in this position, and when the left and right pressing posts 34 are bent towards the inside in order to press and fix the stop pawl body 6, it can avoid In the initial stage of bending, the pressing column 34 is in contact with the corners of the stop pawl 6 . In addition, the pressing posts 34 are bent to some extent and are pressed from above to come into contact with the stop pawls 6 , so that fluctuations in the contact positions between the left and right pressing posts 34 and the stop pawls 6 can be suppressed. Therefore, it is less likely to cause a pressing failure than conventionally.

FIG. 11 shows the state of the pressing pin 34 at the end of the pressing operation in the slider of the third embodiment. At this time, the left and right inner surfaces 41 of the bases of the pair of pressing columns 34 are more present on the left and right sides than the shortest part of the width in the left-right direction of the insertion groove 32 (the part sandwiched by the protruding part 35 and the front end 32a of the insertion groove). outside. Furthermore, it can be seen that the distance (D _2′ ) between the inner surfaces of the bases of the pair of pressing posts 34 is greater than the movement distance (d _A′ =d _C′ ) of the stop pawl 6 inserted into the insertion groove 32 toward the left and right.

In addition, in Example 3, when the handle 5 is made to fall on the engagement opening 27 side, the handle fastening and detachment part 36 which engages this handle 5 detachably is not included. Accordingly, the handle main body part 51 does not need to include the left and right cantilever locking pieces 55 . the

As mentioned above, although this invention was demonstrated based on an Example, this invention is not limited to the said Example, Various changes are possible. For example, in the slider of Embodiment 1, the handle 5 is pressed and fixed by the handle holding part 31 protruding from the upper wing plate 21 of the slider main body 2, but as long as the stop claw body 6 is pressed and fixed on the slider On the premise of the main body 2, for example, the type which attaches the handle 5 to the slider main body 2 through the cover body (not shown) fitted in the slider main body 2 is also possible. Moreover, in Embodiment 1, there is a step portion 38 at the junction between the side wall 39 of the insertion groove and the inner surface 41 of the compression column, but it can also be from the side wall 39 of the insertion groove to the inner surface 41 of the compression column. The continuous tapered surface is formed to cancel the step portion 38 . the
