  And in the end side latching piece 321, the rod-shaped part 328 formed in the opposite side with respect to the opening 319 side of the connection part 329 is formed so that it may extend toward the opposite side from the opening 319 side. A gap is also formed between the rod-shaped portion 328 and the first inner wall portion 311. Here, the rod-shaped portion 328 is connected to the connecting portion 329 at an angle, and the gap between the rod-shaped portion 328 and the first inner wall portion 311 is constant along the extending direction of the rod-shaped portion 328. It is comprised so that it may become. The extending direction of the rod-shaped portion 328 coincides with the extending direction of the insertion hole 31 and the inserting direction.

  The connecting portion 329 and the rod-like portion 328 are configured to be elastically deformable so as to approach the first inner wall portion 311 side when the bracket 9 is inserted into the insertion hole 31. Here, the rod-shaped portion 328 is mainly elastically deformed so as to approach the first inner wall portion 311 side when the bracket 9 is inserted into the insertion hole 31.

  The rod-shaped portion 328 is provided with a locking claw 327. The locking claw 327 is provided on the opposite side to the first inner wall 311 side of the rod-shaped portion 328. That is, the locking claw 327 is provided so as to protrude toward the second inner wall 312 side of the rod-shaped portion 328.

  In the present embodiment, each of the plurality (three in this case) of the locking pieces 32 gradually protrudes from the side (opening 319 side) where the bracket 9 is inserted into the mounting portion 3 toward the opposite side, and is inclined. It includes a portion where a surface is formed. Here, the locking claw 327 in the locking piece 32 is a portion where the inclined surface is formed by gradually protruding from the opening 319 side toward the opposite side. In this case, the rod-shaped portion 328 is pushed closer to the first inner wall portion 311 side by being further inserted in a state where the bracket 9 is in contact with the inclined surface of the locking claw 327. Therefore, since the inclined surface is formed on the locking claw 327, the bracket 9 can be smoothly inserted into the insertion hole 31 of the attachment portion 3.

  In the present embodiment, the center side locking piece 322 (second locking piece) is also connected to the connecting portion 329 and the rod-like portion formed on the opposite side with respect to the opening 319 side of the connecting portion 329 as described above. 328 and a locking claw 327 formed on the rod-shaped portion 328. In the central locking piece 322, the connecting portion 329 protrudes from the second inner wall portion 312 so that the gap between the second inner wall portion 312 and the opening portion 319 gradually increases from the opening 319 side to the opposite side. Is formed. The rod-shaped portion 328 is formed so as to extend from the opening 319 side toward the opposite side, and a gap is also formed between the rod-shaped portion 328 and the second inner wall portion 312. Here, the gap between the rod-shaped portion 328 and the second inner wall portion 312 is configured to be constant along the extending direction of the rod-shaped portion 328. The locking claw 327 provided on the rod-shaped portion 328 is provided so as to protrude toward the first inner wall 311 side of the rod-shaped portion 328.

  Next, the details of the locking hole 8 formed in the bracket 9 will be described. In the present embodiment, the locking hole 8 includes a first inner edge portion 81 extending along the width direction of the attachment portion 3 and a pair of first and second edges in a state where the bracket 9 is inserted into the insertion hole 31 of the attachment portion 3. Two inner edge portions 82. The pair of second inner edge portions 82 exists on the opening 319 side of the first inner edge portion 81 in a state where the bracket 9 is inserted into the insertion hole 31 of the attachment portion 3, and the opening 319 side from the first inner edge portion 81 side. It extends so that the width in between is gradually narrowed toward.

  Here, as shown in FIGS. 1, 7, and 8, the pair of second inner edge portions 82 are connected by a portion on the opening 319 side. The other end is connected to one end of the first inner edge 81 with respect to one end where the second inner edges 82 of one of the pair of second inner edges 82 are connected. The other end of the pair of second inner edges 82 is connected to the other end of the first inner edge 81 with respect to one end where the second inner edges 82 are connected to each other.

  Therefore, in the present embodiment, the locking hole 8 is formed in a triangular shape surrounded by the pair of second inner edge portions 82 and the first inner edge portion 81. A case where the locking hole 8 is a hole other than a triangular shape is also conceivable. For example, a case where the pair of second inner edge portions 82 are connected via the third inner edge portion along the width direction of the attachment portion 3 at the end portion on the opposite side to the end portion on the first inner edge portion 81 side is also considered. It is done. In this case, the locking hole 8 of the bracket 9 may be trapezoidal. Further, in addition to the third inner edge portion, the locking hole 8 includes a pair of fourth inner edge portions that connect both end portions of the first inner edge portion 81 and the end portions of the pair of second inner edge portions 82. In this case, it is conceivable that the locking hole 8 has a hexagonal shape.

  Of course, the case where the locking hole 8 has a circular shape, a rectangular shape, or a rounded square shape is also conceivable. For example, when the locking hole 8 has a rectangular shape, the locking pieces 32 may come into contact with the inner edge portions on both sides of the locking hole 8 and become locked.

  Next, with reference to FIGS. 7 and 8, the locked state of the bracket 9 and the attachment portion 3 in the wire harness fixing structure 100 will be described.

  In the present embodiment, first, the bracket 9 is inserted into the insertion hole 31 through the opening 319 of the attachment portion 3. Eventually, the tip of the bracket 9 comes into contact with the locking claws 327 of the three locking pieces 32 provided in the insertion hole 31.

  Then, with the tip of the bracket 9 in contact with the locking claw 327, the bracket 9 is inserted further into the back, so that the rod-shaped portion 328 is pushed and extended through the locking claw 327, and the end side locking The rod-shaped portion 328 of the piece 321 is elastically deformed so as to approach the first inner wall portion 311 side, and the rod-shaped portion 328 of the center side locking piece 322 approaches the second inner wall portion 312 side. Here, when a predetermined amount of the bracket 9 is inserted, the locking claws 327 of the three locking pieces 32 can enter the locking holes 8 of the bracket 9 and the rod-shaped portion 328 returns to its original shape. . Accordingly, the three locking claws 327 come into contact with the first inner edge portion 81 and the pair of second inner edge portions 82 of the locking hole 8, and the movement of the bracket 9 with respect to the attachment portion 3 is suppressed.

  More specifically, in the present embodiment, each of the locking claws 327 in the two end side locking pieces 321 of the three locking pieces 32 is a pair of second inner edge portions 82 of the locking hole 8 of the bracket 9. By abutting on each, the bracket 9 is restricted from moving in the width direction of the mounting portion 3.

  Further, the locking claw 327 in the two end side locking pieces 321 and the locking claw 327 in the center side locking piece 322 abut on the first inner edge portion 81, so that the bracket 9 moves in the insertion direction. Is regulated.

  Further, as in this embodiment, the locking hole 8 includes a pair of second inner edge portions 82, and each of the plurality of locking pieces 32 is on the opposite side from the side where the bracket 9 is inserted into the mounting portion 3. The following merit can be acquired when it includes the part which protruded gradually toward the surface and the inclined surface is formed.

  That is, in this embodiment, as shown in FIG. 8, the pair of second inner edge portions 82 extending so that the width between the first inner edge portion 81 side and the opening 319 side gradually decreases. The pawl 327 comes into contact with the edge portion on the second inner edge portion 82 side. Here, when a force for moving the locking claw 327 in the width direction of the mounting portion 3 is applied, the locking claw 327 is sandwiched between the second inner edge portion 82 and the first inner edge portion 81, and The movement of the locking claw 327 in the locking hole 8 is more effectively restricted.

  Further, in addition to the above configuration, when the locking claw 327 is formed so as to gradually protrude from the opening 319 side toward the opposite side and includes an inclined surface, the end side locking at the pair of second inner edge portions 82 is performed. The locking claw 327 and the locking hole 8 can be locked by contacting any part of the inclined surface with the part 321 side (first main surface 91 side). At this time, for example, even when the shape of the locking claw 327 is slightly larger or smaller due to the dimensional tolerance of the locking piece 32, any part of the inclined surface is on the first main surface 91 side of the second inner edge portion 82. It is possible to contact the part. When the size of the shape of the locking claw 327 is slightly different, the locking claw 327 of the end side locking piece 321 in the thickness direction of the bracket 9 (direction from the first main surface 91 to the second main surface 92). This is because the first inner surface 91 side portion of the second inner edge portion 82 is in contact with any portion of the inclined surface of the locking claw 327. As a result, in the present embodiment, the locking piece 32 and the locking hole 8 can be locked more reliably.

<Effect>
As described above, in the present embodiment, the plurality of locking pieces 32 of the mounting portion 3 are locked in one locking hole 8 among the at least one locking hole 8 formed in the bracket 9. In this case, since the number of the locking pieces 32 to be locked with respect to the one locking hole 8 is large, the locking state between the bracket 9 and the mounting portion 3 can be further strengthened.

  Moreover, in this embodiment, it can suppress more reliably that the bracket 9 moves to the width direction with respect to the attaching part 3 by the two end side latching pieces 321.

  Moreover, in this embodiment, the 1st locking piece and the 2nd locking piece exist in the 1st main surface 91 side and the 2nd main surface 92 side of the bracket 9, respectively. In this case, it becomes easy to insert the bracket 9 into the insertion hole 31.

  Moreover, in this embodiment, it becomes easy to insert the bracket 9 along the inclined surface of the locking piece 32. Further, as described above, the locking hole 8 includes a pair of second inner edge portions 82, and each of the plurality of locking pieces 32 faces from the side where the bracket 9 is inserted into the mounting portion 3 to the opposite side. If the shape of the locking claw 327 of the locking piece 32 is slightly larger or smaller due to, for example, the dimensional tolerance of the locking piece 32, it is more reliable. Thus, the locking piece 32 and the locking hole 8 can be locked.

  In the present embodiment, the plurality of locking pieces 32 abut on the first inner edge 81 and the pair of second inner edges 82 of the locking hole 8 of the bracket 9, so that the bracket 9 is inserted in the insertion direction and width. Restrict movement in the direction. Here, the pair of second inner edge portions 82 extend toward the opening 319 side where the bracket 9 in the attachment portion 3 is inserted so that the width therebetween is gradually narrowed. In this case, it is possible to more reliably create a situation in which two locking pieces 32 existing at both ends of the plurality of locking pieces 32 are in contact with the first inner edge 81 while being in contact with the pair of second inner edges 82. Can do.

<Application example>
In the above embodiment, the two end side locking pieces 321 in the attachment portion 3 are both provided on the first main surface 91 side of the bracket 9. However, it is also conceivable that one of the two end-side locking pieces 321 in the attachment portion 3 is provided on the first main surface 91 side of the bracket 9 and the other is provided on the second main surface 92 side of the bracket 9. It is done.

  Moreover, the case where the hole for locking other than the one locking hole 8 locked with the some locking piece 32 is provided in the bracket 9 is also considered.
