The convex portion 23 is located near the latch operating portion 24 . The convex portion 23 is provided to prevent the latch operating portion 24 from being erroneously operated when the power tool 1 is placed horizontally. The convex portion 23 and the latch operating portion 24 form the outermost surface of the battery pack 20 in the left-right direction, and protrude outward from the plate member 30 described below in the left-right direction. That is, the plate member 30 is located inside the outermost surface of the battery pack 20 .

As shown in FIG. 2 etc., the power tool 1 of this embodiment is characterized by mounting the plate member 30 on the outer surface of the enlarged diameter part 2c. As shown in FIG. 6 etc., the plate member 30 is provided on both left and right side surfaces of the diameter-enlarged part 2c. The left and right plate members 30 have mutually symmetrical shapes. In addition, the plate member 30 may be provided only on either left or right side of the diameter-enlarged portion 2c. The plate member 30 has a shape that does not protrude from the side surface of the diameter-enlarged portion 2c. Here, the plate member 30 is made of a magnetic body and metal, but it may be made of resin, synthetic resin, carbon, or the like. Furthermore, if the shapes of the left and right plate members 30 are the same, there is no need to determine whether the plate member 30 is for right or left use, and the installation of the plate member 30 becomes easy.

As shown in FIGS. 8 and 9 , the plate member 30 has a first surface portion 31 , a second surface portion 32 , and a hook portion 33 . The first surface part 31 and the second surface part 32 are both flat surfaces in the illustrated example, but they may also be curved surfaces or concave and convex surfaces. The first face 31 is a plane closer to a vertical plane than the second face 32 . The second face part 32 is connected to the upper part of the first face part 31 . The second face 32 is an example of the main face. The first surface portion 31 and the second surface portion 32 are respectively mounted along or in close contact with the outer surface of the enlarged diameter portion 2c. The first surface portion 31 is provided with a screw insertion hole 34 and a hook insertion hole 35 as hole portions. A convex portion insertion hole 36 is provided across the first face portion 31 and the second face portion 32 . The hook portion 33 and the screw insertion hole 34 are examples of attachment portions for attaching the plate member 30 to the enlarged diameter portion 2c.

As shown in FIG. 4 and others, the enlarged diameter portion 2c is provided with a convex portion 2d, a hook locking hole 2e, a screw hole portion 2f, and a hooked portion 2g. As shown in FIGS. 5 and 6 , the protrusion 2 d is a protrusion that penetrates the protrusion insertion hole 36 of the plate member 30 and protrudes outward from the plate member 30 . The top of the convex portion 2d forms the outermost surface of the enlarged diameter portion 2c in the left-right direction. The plate member 30 is located inside the top of the convex portion 2d in the left-right direction when attached to the diameter-enlarged portion 2c. As shown in FIGS. 6 and 7 , at least part of the surface of the enlarged diameter portion 2 c includes the elastic body 2 p, and the surface of the convex portion 2 d also includes the elastic body 2 p. That is, the outermost surface of the enlarged diameter portion 2c in the left-right direction contains the elastic body 2p. The convex portion 2d serves as a grounding portion when the power tool 1 is placed horizontally, thereby suppressing damage to the table top or target materials.

The hook locking hole 2e is a hole for inserting and locking the base end of the hook 16 shown in FIG. 15 . The base end of the hook 16 penetrates the hook insertion hole 35 of the plate member 30 and is inserted into the hook locking hole 2e. The screw hole portion 2f is provided to fasten the screw 15 of the fixing plate member 30 and the hook 16. The screw 15 penetrates the screw insertion hole 34 of the plate member 30 and is screwed to the screw hole portion 2f. The screw 15 is also used to secure the hook 16. When both the hook 16 and the plate member 30 are attached to the enlarged diameter part 2c, the screw 15 penetrates the through hole 16a of the hook 16 and the screw insertion hole 34 of the plate member 30, and is screwed to the screw hole part 2f. The hooked portion 2g is a portion that hooks (locks) the hooking portion 33 of the plate member 30 .

The plate member 30 can be used to add various additional functions. 10 and 11 illustrate an example in which the bit holder 17 is provided on the second surface portion 32 of the plate member 30 using the magnetic force of the permanent magnet 37. The permanent magnet 37 may be integrally provided on the second surface 32 of the plate member 30 , or may be integrally provided on the bit holder 17 , or may be separate from the plate member 30 and the bit holder 17 and provided on the plate member 30 and the bit. between retainers 17. At least one of the bit holder 17 and the plate member 30 is made of a magnetic body. The bit 18 is held by the bit holder 17 . This makes it easier to take the bit 18 and improves workability. As shown in FIGS. 12(A) and 12(B) , the bit holder 17 is rotatable relative to the plate member 30 . This allows the operator to hold the bit 18 in a desired orientation, thereby improving workability. In addition, the permanent magnet 37 can be positioned on the surface of the first face portion 31 and the bit holder 17 can be provided on the first face portion 31 .

13 and 14 show an example in which a permanent magnet 37A is provided on the back surface of the second surface portion 32 of the plate member 30 and the bit 18 and the screw 18A are held on the second surface portion 32 . The permanent magnet 37A is not visible to the operator. The bit 18 and the screw 18A are attracted to the surface of the second surface portion 32 of the plate member 30 by the magnetic force of the permanent magnet 37A. This makes it easy to access the bit 18 or the screw 18A, thereby improving workability. In addition, the permanent magnet 37A may be provided on the back surface of the first surface part 31 to hold the bit 18 and the screw 18A on the first surface part 31 . Alternatively, permanent magnets 37A may be provided on the back surfaces of both the first face part 31 and the second face part 32 to hold the bit 18 and the screw 18A on the surfaces of both the first face part 31 and the second face part 32 . The plate member 30 may hold a tip tool other than the bit 18 and the screw 18A, a fastener, or the like as a magnetic accessory.

FIG. 15 shows an example in which the plate member 30 and the hook 16 are attached to the enlarged diameter portion 2c. The plate member 30 and the hook 16 can be simultaneously attached to the enlarged diameter portion 2c using a common screw 15. External components can be hooked on the hook 16 . The hook 16 can be attached to the enlarged diameter portion 2 c together with the plate member 30 , and the bit holder 17 or the bit 18 or the screw 18A can be sucked onto the plate member 30 as shown in FIGS. 12(A) to 14 . In the case where the bit holder 17 interferes with the hook 16, just select one with a smaller size than the bit holder 17.

According to this embodiment, the following effects can be exerted.

(1) Since the plate member 30 is attached to the surface of the enlarged diameter portion 2c, it is less likely to hinder the operator from holding the handle portion 2b. The enlarged diameter portion 2c is located on the opposite side of the anvil 8 and the like with the handle portion 2b interposed therebetween. Therefore, when the operator observes the tip tool mounted on the anvil 8, the plate member 30 is less likely to interfere (is less likely to enter the line of sight). Furthermore, by assembling the plate member 30, the strength of the diameter-enlarged portion 2c can be improved.

(2) The plate member 30 follows the outer surface of the enlarged diameter portion 2c or is in close contact with it. Furthermore, the plate member 30 is located inside the enlarged diameter portion 2 c and the outermost surface of the battery pack 20 in the left-right direction. Therefore, it is possible to suppress the plate member 30 from interfering with work, and also to suppress an increase in the size of the power tool 1 due to the assembly of the plate member 30 . Furthermore, damage to the plate member 30 can also be suppressed.

(3) By installing the plate member 30, the operator can easily distinguish his or her own power tool 1 from other power tools of the same type that do not have the plate member 30 installed. The color of the plate member 30 may be selected from a variety of colors. In this case, the operator can easily distinguish his or her own power tool 1 from the power tool 1 equipped with the plate member 30 of another color. Furthermore, the owner's name can be written on the plate member 30 by laser engraving or the like, or it can be decorated by water transfer printing, painting, or plating, thereby further expressing creativity. Making the appearance of the power tool 1 unique (the ease of distinguishing it from other power tools of the same type) through the plate member 30 is also one of the additional functions of the plate member 30 . By making the appearance unique, it can also satisfy the operator's desire for a tool that looks different from others.

(4) Various additional functions can be added through the plate member 30, which is convenient. For example, accessories such as the bit 18 and the screw 18A can be easily stored and held, which is convenient.

(5) The hook 16 may be attached to the enlarged diameter portion 2c together with the plate member 30, which is convenient for the operator who uses the hook 16. The plate member 30 and the hook 16 are fixed using the common screw 15 and the screw hole portion 2f. Therefore, the plate member 30 and the hook 16 can be easily attached, and the increase in the diameter of the enlarged diameter portion 2c can be suppressed.

(Other Embodiments) FIG. 16 and FIG. 17 relate to Embodiment 2 of the present invention. The expanded diameter portion 2cA has a larger planar portion substantially perpendicular to the left-right direction among both side surfaces than the expanded diameter portion 2c. Plate members 30A are attached to the planar portions of both side surfaces of the enlarged diameter portion 2cA. The plate member 30A has a hook portion having the same structure as the hook portion 33 of the plate member 30. The portion other than the hook portion is a plane substantially perpendicular to the left-right direction and is along or in close contact with both side surfaces of the enlarged diameter portion 2cA. The plate member 30A has a shape that does not protrude from the side surface of the diameter-enlarged portion 2cA. Like the plate member 30 , the plate member 30A is assembled to the enlarged diameter portion 2cA by the locking of the hook portion and the tightening force of the screw 15 . Like the plate member 30 , additional functions can be added to the plate member 30A.

18 and 19 relate to Embodiment 3 of the present invention. The enlarged diameter portion 2cB is different from the enlarged diameter portion 2cA in having the rib portion 2h surrounding the entire circumference of the plate member 30A, but is the same in other aspects. The rib portion 2h is a protruding portion that is positioned at the same position as the plate member 30A in the left-right direction, or preferably extends further outside. The rib 2h can suppress the shaking of the plate member 30A, and can also suppress objects from being caught on the edges of the plate member 30A. The ribs 2h can reduce the impact when the plate member 30A is placed on the lower side and the power tool is placed on a workbench or the like, and the plate member 30A can be protected from damage by external force.
