Description

  The present invention relates to a female terminal and a connector, for example, a female terminal that conducts by sandwiching a band-shaped inserter, and a connector having such a female terminal.

  Conventionally, the female terminal 50 as shown in FIG. 31 is known (for example, refer patent document 1).

  The female terminal 50 illustrated in FIG. 31 includes an electrical contact portion 51 and a wire connection portion 52 that is connected to the electrical contact portion 51 and to which an electric wire (not shown) is attached. The electrical contact portion 51 includes a tubular tubular portion 53 and an elastic contact piece 54 that is bent so as to be accommodated in the tubular portion 53 and is elastically deformable. The strip-shaped male tab 56 of the mating male terminal 55 enters the cylindrical portion 53, that is, the electrical contact portion 51.

  The male terminal 55 includes a strip-shaped male tab 56 and an electric wire connecting portion (not shown) connected to the male tab 56 and to which an electric wire is attached.

When the male tab 56 enters the cylindrical portion 53, the male tab 56 contacts the elastic contact piece 54. Then, the elastic contact piece 54 urges the male tab 56 toward the inner surface of the cylindrical portion 53. Thus, the female terminal 50 and the male terminal 55 are electrically connected with the male tab 56 sandwiched between the inner surface of the cylindrical portion 53 and the elastic contact piece 54. Further, at this time, the elastic contact piece 54 is in contact with the top portion 57 of the male tab 56.

  In the female terminal 50 having the above-described configuration, the male tab 56 is in contact with the top 57 of the elastic contact piece 54. Therefore, when the male tab 56, that is, the male terminal 55 vibrates in the direction intersecting the insertion direction, the male tab 56. However, it may vibrate so as to rotate about the top 57. Then, the contact point between the male tab 56 and the female terminal 50 is relatively displaced, and the so-called male terminal 55 and the female terminal 50 may be slightly worn. If this fine sliding wear occurs, the electrical resistance value between the terminals 50 and 55 is increased, which is not desirable.

  Therefore, an object of the present invention is to prevent vibration of the inserter of the mating male terminal, to prevent the occurrence of fine sliding wear and to increase the electrical resistance value with the mating male terminal, and To provide a connector.

It is characterized by having a regulating member .

According to the female terminal of the present invention described in claim 1, the inserter inserted into the cylindrical portion is supported at the base end portion side by the base end portion side support portion and vibrates at the tip end portion side by the vibration regulating portion. Since this is regulated, it is possible to support two locations on the proximal end side and the distal end side of the inserter. For this reason, it can restrict | limit that the inserter accommodated in the cylinder part rotates centering on a contact.
Since the restricting member restricts the distal end portion side of the inserter from being separated from the inner surface of the cylindrical portion by a certain distance or more, the two locations of the proximal end portion side and the distal end portion side of the inserter can be reliably supported. For this reason, it can restrict | limit that the inserter accommodated in the cylinder part rotates centering on a contact.

As described above, according to the first aspect of the present invention, in the inserter inserted into the cylindrical portion, the base end portion side is supported by the base end portion side support portion, and the tip end portion side is vibrated by the vibration regulating portion. Since this is restricted, it is possible to support two locations on the proximal end side and the distal end side of the inserter. For this reason, since the inserter accommodated in the cylindrical portion can be prevented from rotating around the contact point, the female terminal of the present invention prevents vibration of the inserter of the other male terminal and prevents fine sliding wear. It can be prevented that the electrical resistance value with the male terminal of the other party is raised.
Since the restricting member restricts the distal end portion side of the inserter from being separated from the inner surface of the cylindrical portion by a certain distance or more, the two locations of the proximal end portion side and the distal end portion side of the inserter can be reliably supported. For this reason, since the inserter accommodated in the cylindrical portion can be prevented from rotating around the contact point, the female terminal of the present invention prevents vibration of the inserter of the other male terminal and prevents fine sliding wear.

  In the present embodiment, the electrical connection portion 12 includes a second regulating member 28 in addition to the spring piece 18 and the regulating member 25.

  The configuration of the spring piece 18 is substantially the same as the spring piece 18 of the first embodiment described above, and includes a top portion 20. The top portion 20 is provided at the other end portion 23 (side) of the spring piece 18. The top portion 20 is curved and formed so that the spring piece 18 can be brought close to the ceiling wall 13. The top portion 20 is a position closest to the ceiling wall 13 in the other end portion 23 of the spring piece 18. The top part 20 mounts the inserter 5 that has entered the cylindrical part 11 on the surface thereof.

  The spring piece 18 is elastically deformable so that the top portion 20 is displaced in a direction approaching the bottom wall 9b.

Therefore, as shown in FIGS. 13A and 13B, the introducing portion 19 guides the inserter 5 between the spring piece 18 and the contact wall 15 of the cylindrical portion 11.

  Along with the top 20 of the spring piece 18 urging the base end side 24 of the insert 5 toward the ceiling wall 13, that is, the other end 23, the base end side 24 of the insert 5 is more than a certain distance from the inner surface of the cylindrical portion 11. The second restricting member 28 configured as described above for restricting the separation constitutes the base end side support portion 16 that supports the base end side 24 of the inserter 5. That is, in the present embodiment, the top portion 20, that is, the other end portion 23 of the spring piece 18 and the second restricting member 28 constitute the base end side support portion 16.

Then, the inserter 5 comes into contact with the introduction portion 19 and the inclined surface of the contact wall 15 on the inserter 5 side. Then, as the inserter 5 moves along the arrow K, the inserter 5 is guided by the introduction portion 19 and the inclined surface and guided between the top portion 20 of the spring piece 18 and the contact wall 15. .

  Then, as the inserter 5 moves along the arrow K, the inserter 5 resists the elastic restoring force of the spring piece 18 and spreads between the top 20 and the contact wall 15. 18 is elastically deformed. Then, as shown in FIG. 13 (b), when the inserter 5 is inserted into the tube portion 11 along the arrow K, the base end side 24 of the inserter 5 contacts the top portion 20 of the spring piece 18. It is positioned between the wall 15. Then, the distal end portion side 26 of the inserter 5 is opposed to the restricting member 25, the proximal end portion side 24 is opposed to the second restricting member 28, and between the top portion 20 of the spring piece 18 and the contact wall 15.

A vibration restricting portion 17 that restricts this is configured. As described above, the vibration restricting portion 17 restricts the distal end portion 26 of the inserter 5 from vibrating by restricting the inserter 5 from being separated from the inner surface of the cylindrical portion 11 by a certain amount or more.

  The top 20, that is, the other end 23 of the spring piece 18 urges the base end 24 of the insert 5 toward the ceiling wall 13, and the base end 24 of the insert 5 extends from the inner surface of the cylindrical portion 11 to a certain level or more. When the restriction plate 29 restricts the separation, the top portion 20 of the spring piece 18, that is, the other end portion 23 and the second restriction member 28 support the proximal end portion side 24 of the inserter 5. 16 is configured.

  As described above, the proximal end side support portion 16 and the vibration restricting portion 17 can reliably support the two locations of the proximal end portion side 24 and the distal end portion side 26 of the inserter 5. For this reason, since it can restrict | limit that the inserter 5 accommodated in the cylinder part 11 rotates centering on a contact, the female terminal 3 of this invention prevents the vibration of the inserter 5 of the other male terminal 4. It is possible to prevent an increase in electrical resistance with the mating male terminal 4 due to fine sliding wear.

  Further, as shown by a dotted line in FIG. 20, the distal end side 26 of the inserter 5 inserted into the cylindrical portion 11 rotates about the top portions 20a and 20b of the spring pieces 18a and 18b toward the bottom wall 9b. In this case (as indicated by an arrow p1 in FIG. 20), the distal end side 26 of the inserter 5 pushes the other end 23a of the spring piece 18a toward the bottom wall 9b as indicated by an arrow p4. For this reason, the distal end portion side 26 of the inserter 5 and the other end portion 23a of the spring piece 18a remain in contact with each other. Further, at this time, as shown by an arrow p2, the inserter 5 comes into contact with the edge of the end wall 33a near the end wall 33b. Then, the insert 5 rotates about the edge of the end wall 33a near the end wall 33b, and as shown by an arrow p3, the base end side 24 of the insert 5 bottoms the top 20b of the spring piece 18b. Push towards wall 9b. As a result, the spring piece 18b has its top portion 20b biasing the base end side 24 of the inserter 5 toward the ceiling wall 13 and is entirely displaced toward the bottom wall 9b as shown by the dotted line in FIG. To do. Then, as in the case where the entire inserter 5 is swung toward the bottom wall 9b, the other end 23b of the spring piece 18b follows the contact point a of the spring piece 18a, and the whole spring piece 18a is shown in FIG. As shown by the dotted line, it is displaced in conjunction with the spring piece 18b.

  Further, the distal end portion side 26 of the inserter 5 inserted into the cylindrical portion 11 rotates about the top portions 20a and 20b of the spring pieces 18a and 18b toward the ceiling wall 13 (indicated by an arrow q1 in FIG. 20). In the case of swinging, as shown by the arrow q2, the inserter 5 comes into contact with the edge of the end wall 33b near the end wall 33a. Then, the insert 5 rotates around the edge of the end wall 33b near the end wall 33a, and as shown by an arrow q3, the base end side 24 of the insert 5 ceilings the top 20a of the spring piece 18a.

Then, as in the case where the entire inserter 5 is swung toward the ceiling wall 13, the spring piece 18a has the top portion 20a urging the base end side 24 of the inserter 5 toward the bottom wall 9b. The whole is displaced toward the ceiling wall 13. Then, the other end portion 23a of the spring piece 18a follows the distal end portion side 26 of the insert 5 and remains in contact with the distal end portion side 26 of the insert 5 as indicated by an arrow q4.

According to this reference example , the top portions 20a, 20b, that is, the one end portion 21 of the pair of spring pieces 18a, 18b are sandwiched between the proximal end portion sides 24 of the inserter 5 so that the proximal end portion of the inserter 5 is sandwiched between them. The base end side support part 16 which supports the side 24 is comprised. In this way, the base end side support portion 16 supports the base end portion side 24 of the insert 5 by sandwiching the insert 5 between the end portions 21 of the pair of spring pieces 18a and 18b.

Since the other end portion 23a of one spring piece 18a restricts the vibration of the distal end portion side 26 of the inserter 5, the inserter 5 inserted into the cylindrical portion 11 is bent. Even if it vibrates as indicated by x1, y1, p1, q1, as described above, the entire spring pieces 18a, 18b are displaced, and the distal end side 26 of the insert 5 and the other end 23a of the spring piece 18a are displaced. And remain in contact. For this reason, between the one end parts 21 of the spring pieces 18a and 18b urges (elastically deforms) the base end side 24 of the inserter 5 toward the inside of the cylindrical part 11, and the other end part 23a of the spring piece 18a is inserted.

That is, the cylindrical part 34 is continued to the other end part 23 of each of the pair of spring pieces 18a and 18b, that is, the free end. As for the cylindrical part 34, the front-end | tip part side 26 of the inserter 5 penetrate | invades. When the inserted insert 5 vibrates, the tubular portion 34 abuts the distal end side 26 of the insert 5 on the inside thereof, and the distal end side 26 of the insert 5 is brought into the inner side of the tubular portion 34. Energize to. In other words, the tubular portion 34, that is, the other end portion 23 of the spring pieces 18 a and 18 b is brought into contact with the distal end portion side 26 of the insert 5 that has entered the tubular portion 34, so that the distal end portion of the insert 5. The vibration restricting portion 17 is configured to restrict the side 26 from vibrating. As described above, the vibration restricting portion 17 is configured so that the tubular portion 34, that is, the other end portion 23 of the spring pieces 18 a and 18 b is brought into contact with the inserter 5 that has entered the inside of the tubular portion 34. The vibration of the tip end side 26 is regulated.

According to this reference example , the protrusions 35 of the spring pieces 18 a and 18 b, that is, the one end portion 21 urge the base end side 24 of the insert 5 toward the inside of the tube portion 11, thereby The base end side support portion 16 that supports the end side 24 is configured.

The vibration regulation 17 which regulates that the front-end | tip part side 26 vibrates is comprised. In this way, the vibration restricting portion 17 makes the distal end of the insert 5 by bringing the tubular portion 34, that is, the other end 23 of the spring pieces 18 a and 18 b into contact with the insert 5 that has entered the inside of the tubular portion 34. The part side 26 is restricted from vibrating.

  Further, the protrusion 35 of the spring pieces 18a and 18b, that is, the one end portion 21 urges the proximal end side 24 of the insert 5 toward the inner surface of the cylindrical portion 11, and the cylindrical portion 34, that is, the other ends of the spring pieces 18a and 18b. Since the portion 23 is brought into contact with the distal end portion side 26 of the inserter 5 that has entered the inside of the cylindrical portion 34, the distal end portion side 26 of the inserter 5 is restricted from vibrating, so that the inserter 5 can be surely inserted. The base end side 24 and the tip end side 26 can be supported at two locations. For this reason, since it can restrict | limit that the inserter 5 accommodated in the cylinder part 11 rotates centering on a contact, the female terminal 3 of this invention prevents the vibration of the inserter 5 of the other male terminal 4. It is possible to prevent an increase in electrical resistance with the mating male terminal 4 due to fine sliding wear.

Next, a female terminal according to a fifth reference example of the present invention will be described with reference to FIGS. The same components as those in the first and second embodiments and the first to fourth reference examples described above are denoted by the same reference numerals and description thereof is omitted.

In this reference example , the electrical connection portion 12 of the electrical contact portion 8 includes a curved piece 36 and an indent 37, as shown in FIGS. 24 (a), 24 (b) and 25 (a). . A pair of the curved pieces 36 are provided in the illustrated example. One curved piece 36 (hereinafter denoted by reference numeral 36a) is provided on the bottom wall 9b, and the other curved piece 36 (hereinafter denoted by reference numeral 36b) is provided on the ceiling wall 13. The curved piece 36a is provided at the end of the bottom wall 9b away from the electric wire connecting portion 7. The curved piece 36b is provided at the end of the ceiling wall 13 near the electric wire connecting portion 7. Thus, the pair of curved pieces 36a and 36b are displaced from each other along the arrow K. As described above, the pair of curved pieces 36 a and 36 b are provided along the arrow K. That is, a plurality of curved pieces 36 a and 36 b are provided along the arrow K.

  Each of the curved pieces 36a and 36b includes a disk-shaped central portion 38 and a plurality of connecting pieces 39. The plurality of connecting pieces 39 are arranged around the central portion 38 at intervals. That is, the slit 40 is provided between the connecting pieces 39 that are adjacent to each other. The plurality of connecting pieces 39 of the curved piece 36 a connect the central portion 38 and the bottom wall 9 b of the cylindrical portion 11. The plurality of connecting pieces 39 of the curved piece 36 b connect the central portion 38 and the ceiling wall 13 of the cylindrical portion 11.

  The curved pieces 36a and 36b are formed by bending the central portion 38 and the connecting piece 39 so that the central portion 38 is positioned inside the cylindrical portion 11 with respect to the walls 9b and 13 of the cylindrical portion 11. The curved piece 36a is curved toward the inside of the cylindrical portion 11 in a direction away from the bottom wall 9b of the bottom wall 9b. The curved piece 36b is curved toward the inside of the cylindrical portion 11 in a direction away from the ceiling wall 13 of the ceiling wall 13. The curved pieces 36 a and 36 b are formed by punching (curving) a part of the bottom wall 9 b and the ceiling wall 13 of the cylindrical portion 11 toward the inside of the cylindrical portion 11.

  The curved piece 36a having the above-described configuration is elastically deformable so that the central portion 38 is displaced in a direction away from the ceiling wall 13. The curved piece 36b configured as described above is elastically deformable so that the central portion 38 is displaced in a direction away from the bottom wall 9b. The curved pieces 36a and 36b are formed by being bent toward the inside of the cylindrical portion 11 by pressing a tool (also referred to as a mold) such as the punch 43 or the like.

  A pair of indents 37 is provided in the illustrated example. One indent 37 (hereinafter denoted by reference numeral 37a) is provided on the ceiling wall 13, and another indent 37 (hereinafter denoted by reference numeral 37b) is provided on the bottom wall 9b. The indent 37a is opposed to the curved piece 36a. The indent 37b is opposed to the curved piece 36b.

  The indent 37 a is formed by punching the ceiling wall 13 of the cylinder part 11 toward the inside of the cylinder part 11. The indent 37 b is formed by punching the bottom wall 9 b of the cylinder portion 11 toward the inside of the cylinder portion 11. The indents 37a and 37b protrude toward the inside of the cylindrical portion 11 in a direction away from the bottom wall 9b and the ceiling wall 13 of the cylindrical portion 11. The indent 37a is inclined with respect to the arrow K described above so as to gradually move toward the bottom wall 9b as it goes toward the wire connecting portion 7. The indent 37b is inclined with respect to the arrow K described above so as to gradually move toward the ceiling wall 13 toward the electric wire connecting portion 7. The indents 37a and 37b are not elastically deformed (almost not elastically deformed) even when the inserter 5 is positioned on the surface and pressed by the inserter 5.

  When the insertion piece 5 is inserted between the bending pieces 36a and 36b in the cylindrical portion 11 and the indents 37a and 37b, the bending pieces 36a and 36b come into contact with the central portion 38. As the inserter 5 is inserted into the inner side of the arrow K of the cylindrical portion 11, the central portion 38 of the curved piece 36a is gradually displaced away from the ceiling wall 13, and the central portion 38 of the curved piece 36b is bottomed. It is gradually displaced away from the wall 9b.

  The curved piece 36 a generates an elastic restoring force that urges the inserter 5 toward the ceiling wall 13. The curved piece 36b generates an elastic restoring force that urges the inserter 5 toward the bottom wall 9b. As shown in FIG. 25B, the bending piece 36a sandwiches the proximal end portion side 24 of the inserted insert 5 together with the indent 37a. As shown in FIG. 25B, the bending piece 36b sandwiches the distal end portion side 26 of the inserted insert 5 together with the indent 37b. That is, the pair of curved pieces 36 a and 36 b urge (support) the inserter 5 inserted into the cylindrical portion 11 toward the inner surface of the cylindrical portion 11.

  The bending piece 36a and the indent 37a sandwich the proximal end portion side 24 of the inserter 5 inserted into the cylindrical portion 11 between each other. The curved piece 36b and the indent 37b sandwich the distal end portion side 26 of the inserter 5 inserted into the cylindrical portion 11 between each other. The inserter 5 sandwiched between the curved pieces 36a, 36b and the indents 37a, 37b is formed between the curved piece 36a and the indent 37a even when the inserter 5 vibrates in the direction intersecting the arrow K in the cylindrical portion 11. And between the curved piece 36b and the indent 37b.

  That is, the curved piece 36a and the indent 37a sandwich the proximal end portion side 24 of the insert 5 between each other (biasing it toward the inner surface of the tubular portion 11), whereby the proximal end portion side of the insert 5 is provided. The base end side support portion 16 that supports 24 is configured. Thus, the base end side support part 16 supports the base end part side 24 of the inserter 5 by sandwiching the inserter 5 between the curved piece 36a and the indent 37a. The bending piece 36b and the indent 37b sandwich the distal end portion side 26 of the insert 5 between each other (biasing it toward the inner surface of the cylindrical portion 11), so that the distal end portion side 26 of the insert 5 vibrates. A vibration restricting portion 17 that restricts this is configured. As described above, the vibration restricting portion 17 restricts the distal end portion 26 of the insert 5 from vibrating by sandwiching the insert 5 between the curved pieces 36b and the indent 37b.

  The female terminal 3 is manufactured by bending a sheet metal 27 shown in FIG. 26 punched out so as to form the outer shape of the electric wire connecting portion 7 and the electric contact portion 8.

  The sheet metal 27 is bent at a crease line 41 indicated by a one-dot chain line shown in FIG. 26, and a portion surrounded by a cut-and-raised line 42 indicated by a two-dot chain line in FIG. In addition to forming, indents 37a and 37b are formed by cutting portions indicated by dotted lines in FIG.

  Next, a procedure for forming the curved pieces 36a and 36b will be described. First, a portion surrounded by a two-dot chain line of the metal plate 27 shown in FIG. 26 is punched to form a slit 40 as shown in FIGS. After that, as shown in FIG. 27 (b), the slits 40 described above were formed in the punch 43 having the same outer diameter as the curved pieces 36a and 36b described above and the tip surface curved convexly toward the sheet metal 27. Move closer to the point.

  Then, the front end surface of the punch 43 is pressed against the walls 9 b and 13, and the central portion 38 and the connecting piece 39 are pressed (fired) from the walls 9 b and 13 toward the inside of the cylindrical portion 11. Then, it is bent in a convex shape from the walls 9 b and 13 to the inside of the cylindrical portion 11 across the central portion 38 and the connecting piece 39. Thus, as shown in FIG. 27 (c), the curved pieces 36a and 36b are driven out from the walls 9b and 13 from the central portion 38 to the connecting piece 39 to be formed in the walls 9b and 13 or the cylindrical portion 11. The

According to this reference example , the bending piece 36a and the indent 37a sandwich the proximal end portion side 24 of the insert 5 between each other (biasing toward the inner surface of the tube portion 11), thereby inserting the insert 5 The base end portion side support portion 16 that supports the base end portion side 24 is configured. Thus, the proximal end side support portion 16 sandwiches the inserter 5 between the curved pieces 36a and the indent 37a (biased toward the inner surface of the cylindrical portion 11), thereby inserting the inserter 5 The base end side 24 is supported. The curved piece 36b and the indent 37b constitute a vibration restricting portion 17 that restricts vibration of the distal end portion side 26 of the inserter 5 by sandwiching the distal end portion side 26 of the inserter 5 therebetween. As described above, the vibration restricting portion 17 restricts the distal end portion 26 of the insert 5 from vibrating by sandwiching the insert 5 between the curved pieces 36b and the indent 37b.

  Further, since the base end side support portion 16 and the vibration regulating portion 17 are curved pieces 36a and 36b formed by bending a part of the cylindrical portion 11 toward the inside of the cylindrical portion 11, Even if the inserter 5 accommodated in the portion 11 vibrates in the direction crossing the arrow K, the proximal end side 24 and the distal end side 26 of the inserter 5 are sandwiched (biased toward the inner surface of the tube portion 11). can do. Therefore, even if the inserter 5 sandwiched between the proximal end portion 24 and the distal end portion side 26 (biased toward the inner surface of the tube portion 11) vibrates in the direction intersecting the arrow K, the inserter 5 And the electrical connection portion 12 of the female terminal 3 can be maintained, so that the female terminal 3 of the present invention prevents vibration of the inserter 5 of the other male terminal 4 and slides slightly. It is possible to prevent the electrical resistance value with the mating male terminal 4 from increasing due to wear.

  Further, since it is not necessary to connect the curved pieces 36a and 36b to the edge such as the tip of the cylindrical portion 11, there is no portion extending outward from the cylindrical portion 11 in a state before being bent. Therefore, the yield of the material of the female terminal 3 can be improved. That is, more female terminals 3 can be obtained from the sheet metal 27 constituting the female terminal 3, and a portion other than the female terminal 3 of the sheet metal 27 (a useless portion) can be reduced.

  In addition, the curved pieces 36a and 36b are provided with a disc-shaped central portion 38 and a plurality of portions that are spaced from each other around the central portion 38 and connect the central portion 38 and the walls 9b and 13 of the cylindrical portion 11. Therefore, even if the inserter 5 accommodated in the cylindrical portion 11 vibrates in the direction crossing the arrow K, the proximal end side 24 and the distal end side 26 of the inserter 5 are provided. Is urged toward the inner surface of the cylinder portion 11, the vibration of the inserter 5 can be restricted. Therefore, the base end side 24 is urged toward the base end side support portion 16 toward the inner surface of the cylindrical portion 11, and the distal end portion side 26 is urged toward the vibration restricting portion 17 toward the inner surface of the cylindrical portion 11. Even if the inserter 5 vibrates in the direction crossing the arrow K, the electrical connection between the inserter 5 and the electrical connection portion 12 of the female terminal 3 can be maintained. Thus, it is possible to prevent vibration of the inserter 5 of the mating male terminal 4 and to prevent a slight sliding wear and increase an electrical resistance value with the mating male terminal 4.

  In addition, since the curved pieces 36a and 36b can be reliably provided on the walls 9b and 13 of the cylindrical portion 11, the need to connect the curved pieces 36a and 36b to the edges of the cylindrical portion 11 is reliably eliminated. Therefore, the yield of the material of the female terminal 3 can be improved.

  In the present invention, if the curved pieces 36 are arranged around the central portion 38 with a space therebetween and the central portion 38 and the walls 9b and 13 of the cylindrical portion 11 are connected, FIG. 29 (a), As shown in (b), any number of connecting pieces 39 may be provided, and the connecting pieces 39 may be formed in any shape.

Further, in the present reference example , the curved pieces 36a and 36b are provided on the bottom wall 9b and the ceiling wall 13, but in the present invention, the curved pieces 36a and 36b may be provided on the side wall 14.

In this reference example , curved pieces 36a and 36b and indents 37a and 37b are provided on the bottom wall 9b and the ceiling wall 13, respectively. However, in the present invention, only the curved pieces 36a and 36b may be provided as shown in FIG. In the case shown in FIG. 30, a pair of curved pieces 36a and 36b are provided on the bottom wall 9b and the ceiling wall 13, respectively. Therefore, in the present invention, the proximal end side 24 of the inserter 5 may be sandwiched between the curved pieces 36a facing each other, and the distal end side 26 of the inserter 5 may be sandwiched between the curved pieces 36b facing each other.
