  The bracket body 31 is formed in a flat plate shape that projects laterally from the outer wall portion of the protector 2. At the base end portion of the bracket body 31, angle-shaped rib plates 4 that connect the bracket body 31 and the outer wall portion 21 of the protector 2 are provided on both sides thereof. This prevents the bracket body 31 protruding laterally from the outer wall portion 21 of the protector 2 from being broken.

  A bolt fixing portion 33, which is connected to the bracket body 31 and has a bolt insertion hole 32, is formed at the tip of the bracket body 31. The fixing bolt 5 is inserted into the bolt insertion hole 32 of the bolt fixing portion 33, and the fixing bolt 5 passing through the insertion hole 32 is fixed to the back surface of the vehicle body B through the bolt insertion hole 6 formed in the vehicle body B. The mounting bracket 3 is fixed to the vehicle body B by being screwed to the nut 7.

  In the case of this embodiment, a breaking bracket 8 that is fixed to the vehicle body B together with the mounting bracket 3 by the fixing bolt 5 is provided between the mounting bracket 3 and the vehicle body B. The breaking bracket 8 is a plate extending from the fixing portion 82 with a space from the bracket main body 31 of the mounting bracket 3 and a fixing portion 82 having a bolt insertion hole 81 that overlaps the bolt fixing portion 33 of the mounting bracket 3. And an arm portion 84 that rises from the plate-like portion 83 toward the bracket main body 31 and that has a tip portion that abuts on the bracket main body 31. The breaking bracket 8 is formed by press-molding a metal sheet metal.

  The fixing portion 82 is formed in a boss shape, and its upper end surface 82 a is in contact with the lower surface 33 a of the bolt fixing portion 33 and its lower end surface 82 b is in contact with the surface 9 of the vehicle body B.

  The plate-like portion 83 extending laterally from the outer peripheral portion of the fixed portion 82 is formed such that the upper surface 83a is slightly lowered from the upper end surface 82a of the fixed portion 82, and therefore the plate-like portion 83 is formed in the bracket body. It is formed at a distance from the lower surface 31 a of 31. In addition, the lower surface 83b of the plate-like portion 83 is formed continuously with the lower end surface 82b of the fixing portion 82. For this reason, the lower surface 83b of the plate-like portion 83 is also formed so as to contact the surface 9 of the vehicle body B. Yes.

  The arm portion 84 whose extension end portion of the plate-like portion 83 is raised toward the bracket main body 31 has an acute breaking blade 10a at the tip thereof, and is capable of breaking the bracket main body 31. Part 10 is formed. The breaking blade 10 a at the tip of the breaking portion 10 is located above the upper end surface 82 a of the fixing portion 82.

  In addition, a groove portion 11 as a weak body portion is formed on the lower surface 31a of the bracket body 31 with which the breaking blade 10a of the breaking portion 10 abuts. The groove 11 is formed on the entire lower surface of the mounting bracket 3 in a direction perpendicular to the longitudinal direction of the mounting bracket 3, but may be partially formed on a part of the lower surface. Moreover, it is good also as a thin part which formed the plate | board thickness of the attachment bracket 3 of the part which the said breaking blade 10a contact | abuts smaller than the other part instead of the said groove part 11. FIG.

  Next, the case where the wire harness W attached to the vehicle body B is removed from the vehicle body B using the vehicle component mounting structure 1 configured as described above will be described.

  The protector 2 inserted through the wire harness W is disposed between the mounting bracket 3 and the mounting bracket 3 and the vehicle body B by the fixing bolt 5 that passes through the mounting bracket 3 protruding from the outer wall portion 21 of the protector 2. The broken bracket 8 is fixed to the vehicle body B.

  In order to remove the wire harness W attached in this way from the vehicle body B, an impact force may be applied by hitting the upper surface 31b of the bracket body 31 of the mounting bracket 3 protruding from the protector 2 with a hammer or the like. The bracket main body 31 is displaced downward by the impact force of the hammer, and the breaking blade 10a of the breaking portion 10 of the breaking bracket 8 disposed between the bracket main body 31 and the vehicle body B is the lower surface 31a of the bracket main body 31. The bracket body 31 is broken at the groove 11 portion. As a result, the fixing state by the fixing bolt 5 inserted through the mounting bracket 3 of the protector 2 can be released without loosening the fixing bolt 5, and the protector 2 can be easily and quickly removed from the vehicle body. .

  According to the vehicle component mounting structure 1 of the present embodiment, the breaking bracket 8 fixed to the vehicle body B together with the mounting bracket 3 by the fixing bolt 5 is provided between the mounting bracket 3 of the protector 2 and the vehicle body B. Therefore, only by applying an impact force to the upper surface of the mounting bracket 3, the mounting bracket 3 is displaced downward by the impact force, and the breaking bracket 8 disposed between the mounting bracket 3 and the vehicle body B is provided with the mounting bracket. 3, the mounting bracket 3 can be broken, and the protector 2 fixed to the vehicle body B by a plurality of fixing bolts 5 can be easily and quickly removed from the vehicle body without loosening the fixing bolts 5. .

  Since the vehicle component mounting structure 1 described above enables vehicle components such as the wire harness W to be removed from the vehicle body B very easily and in a short time, workability during vehicle disassembly can be improved. , Vehicle recycling can be promoted.

  Further, the breaking bracket 8 is overlapped with a bolt fixing portion 33 provided with a bolt insertion hole 32 of the mounting bracket 3, and the fixing portion is spaced from the bracket body 31 of the mounting bracket 3. A plate-like portion 83 extending from 82, and an arm portion 84 raised from the plate-like portion 83 toward the bracket main body 31 and having a tip portion abutting against the bracket main body 31, and a tip portion of the arm portion 84 In addition, since the breaking portion 10 that can break the bracket body 31 is formed, the impact force causes the bracket body 31 to be displaced downward by simply applying an impact force to the upper surface 31b of the bracket body 31. The breaking blade 10a of the breaking portion 10 of the breaking bracket 8 disposed between the vehicle body B bites into the lower surface 31a of the bracket body 31 and The socket body 31 can be reliably destroyed easily protector 2, and can be removed from the vehicle body in a short time.

  Further, since the groove portion 11 as the weak body portion is formed in the contact portion of the bracket body 31 with the arm portion 84, the breaking blade 10 a of the breaking portion 10 of the breaking bracket 8 is formed on the lower surface 31 a of the bracket body 31. The bracket body 31 can be reliably broken at the groove 11 portion by biting into the groove 11, and the protector 2 can be easily and quickly removed from the vehicle body.
