６３６２号公報等参照）。FIG. 3 shows the structure of the mounting part of a conventional automobile bumper, in which a box part 2 having a substantially U-shaped cross section is integrally formed on the back surface of a bumper 1 made of synthetic resin. A guide groove 3 is formed in the portion 2,
Furthermore, a circular fitting part 4 is provided on the back wall 2a of this box part 2.
A notch 4 is formed, which includes an entrance portion 4b shaped like a rim and an entrance portion 4b. Then, the retainer 5 with bolts 6 implanted therein is inserted into the guide groove 3 of the box part 2, and the retainer 5 is held in the bumper 1 with the boss part 7 fitted into the fitting part 4a. (For example, Jikko 60-

発明が解決し↓うとする問題点
しかしながら、上記従来の構成にあっては、ボックス部

があった。Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, both the left and right ends of the box portion 2 are open.
The rigidity of the box part 2 is low, especially in the vertical direction.
The problem is that the bumper 1 tends to move up and down due to the weight of the bumper 1 itself and external forces, and is easily damaged in the event of a light collision.
また、ボックス部２の剛性向上を図るために、該ボック

まい、バンパ１の外観品質を損う虞れかめる。Furthermore, if a wall is provided to close the box part 2 in order to improve the rigidity of the box part 2, a sink mark will occur at the joint between the wall and the bumper 1 due to molding shrinkage, and the appearance of the bumper 1 will be reduced. There is a risk that quality will be compromised.

The feature is that a slit is provided between the bumper and the rear surface of the bumper.

って隔てられ、非汲合状態となっている。FIGS. 1 and 2 show an embodiment of the present invention. Similar to the conventional example described above, a roughly U-shaped cross section is formed on the back side of a pumper 1 made of synthetic resin such as urethane resin. A box part 2 is integrally formed, and a guide @3 is formed inside this box part 2.
A notch 4 consisting of a circular fitting part 4a and a linear inlet part 4b is formed in the back wall 2a of. A reinforcing wall 12 for closing the box part 2 is integrally formed on the end surface of the box part 2 opposite to the retainer insertion part 11, and a slit is formed between the reinforcing wall 12 and the back surface of the bumper 1. 13 are provided. That is, although the reinforcing walls 12, the back wall 2a, the upper wall 2b, and the lower wall 2c of the box portion 2 are integrally joined, the bumper 1 itself is separated by the sill 13. and is in an uncoupled state.
従って、上記ボックス部２は、上記補強壁１２によって
一端が閉塞され、背部壁２ａ１上部壁２ｂおよび下部壁

大幅に向上し、特に上下方向に対し変形しにくくなる。Therefore, one end of the box part 2 is closed by the reinforcing wall 12, and the back wall 2a1, the upper wall 2b, and the lower wall 2c are firmly connected to each other, so that its rigidity is greatly improved, especially in the vertical direction. It becomes difficult to deform.
また、補強壁１２が成形収縮しても、上記のこうにバン
