ある。Problems to be Solved by the Invention For example, when a load F acts on the bumper, that is, the bumper reinforcement 6 as shown by the arrow in FIG. 4 during a vehicle collision, the bumper stay 5 is pushed in by this input load F. As the bracket 4 attempts to move in the direction, the bracket 4 is subjected to a pushing force P(
(indicated by the arrow in Figure 5)
There is a problem in that the load cannot be transmitted sufficiently.
これに対して、上記ブラケット４の板厚を増加さＵ゛る

を挿入しナツト８で締め付ければ良い。According to the above embodiment structure, when installing the rear bumper, the bumper stay 5 is inserted into the rear side member, the claws 6 of the bumper stay 5 are inserted into the positioning holes 12 of the side wall 9 of the bracket 4, and the side wall 14 of the bumper stay 5 is attached. The rear bumper is accurately positioned by aligning it with the side wall 9 of the bracket 4, and the bolts 7 are inserted into each mounting hole 13 and 17.
Just insert it and tighten it with nut 8.

ト４は変形せず、そのままりヤサイドメンバｌに荷重分
担される。When the bumper stay 5 is mounted in this manner and an input load F acts on it, this input load F becomes a force that pushes the bumper stay 5, but the pushing force P generated by this pushing force is quickly released from the vertical wall 15 of the bumper stay 5. Since the load is transmitted to the vertical wall 10 of the bracket 4 and acts on the bracket 4 in a shearing direction that improves its strength, the bracket 4 does not deform and the load is directly shared with the opposite side member l.
したがって、人力荷重Ｆはバンパステー５．ブラケット
４を介してロスすることなくリヤサイドメンバｌに伝達
されるのである。Therefore, the human load F is the bumper stay 5. It is transmitted to the rear side member l via the bracket 4 without any loss.
その結果、ブラケット４の板厚を増加さける必要もなく
、ブラケット４の変形を抑え、入力荷重をリヤサイドメ
ンバｌで受けることができる。As a result, there is no need to increase the thickness of the bracket 4, deformation of the bracket 4 can be suppressed, and the input load can be received by the rear side member l.
尚、この発明は上記実施例に限られず、フロントハンバ

いう効果かある。As described in detail, according to the present invention, when transmitting the human force load acting on the bumper from the bumper stay to the bracket, it is applied in a shearing direction from the vertical wall of the bumper stay to the vertical wall of the bracket, which is advantageous in terms of strength. Therefore, deformation of the bracket is suppressed, and the human load can be reliably transmitted to the vehicle body frame member through the bracket.
したがって、ブラケットの強度を高めるため板厚を増加
