間を要することになる。By the way, when the projection of the reinforcement general portion i from the side member a is reduced so that the inclination of the reinforcement bending portion d is tight, the bumper stay b has an outer wall j having an inner wall k. Will be much shorter than. On the other hand, at the time of a wall-to-wall collision, a deformation occurs in the reinforcement b to eliminate the inclination of the bent portion 3b. For this reason, a load acting on the bumper stay b to push the reinforcement fixing portion f outward is applied. If the outer wall j is short, the outer wall j exerts a tension action against this load, and the reinforcement is applied. The ment fixing portion f cannot fall down and be deformed. For this reason, the front end of the side member a is bent outward, and the repair is troublesome.

結固定してある。FIGS. 1 and 2 show a first embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a side member, and a bumper stay 2 is fitted and fixed in a front end opening 1a. Numeral 3 is a reinforcement for supporting a shock absorbing material (not shown), and both ends of the general portion 3a are bent rearward to form a bent portion 3.
The bent portion 3b is fastened and fixed to the bump pasty 2. Since the bump pasty 2 is formed by extrusion of an aluminum alloy, the side member fitting portion 4 is formed.
A closed cross section 6 is formed between the first and second reinforcement fixing portions 5 when viewed in the vertical direction. Flanges 7, 7 extend from both side edges of the side member fitting portion 4, and the flanges 7, 7 are fastened and fixed to brackets 8, 8 fixed to the side member 1.

Extends from the bottom wall 11 of the side member fitting portion 4. Therefore, even if the front wall 12 to which the reinforcement 3 is fixed is inclined, the length L 1 of the outer wall 10 is equal to the length L 2 of the inner wall 9. The outer wall 10
The lengths L 1 , L 2 of the inner wall 9 and the inner wall 9 are set to be larger than the end surface extension δ of the reinforcement 3 at the time of the collision with the wall shown in FIG. A pair of holes 13 for fastening and fixing the reinforcement 3 are formed in the front wall 10.

る。In the event of a wall-to-wall collision shown in FIG. 3, the reinforcement 3 is deformed so as to eliminate the inclination of the bent portion 3b. That is, the end face of the reinforcement 3 is extended outward by δ as shown in FIG. In the present embodiment, the length of the outer wall 10 is increased by extending the outer wall 10 of the bump pasty 2 from the bottom wall 11 of the side member fitting portion 4.
0 does not produce a tension action against the elongation deformation of the reinforcement 3, and the reinforcement fixing portion 5
Will be pushed down to the outside. For this reason, bending deformation does not occur at the front end of the side member 1, and only repair of the bump pasty 2 is required at the time of repair.

Further, as shown in FIG. 4C, when the reinforcement 3 is completely extended, the locking portion 20 starts to be crushed, and the collision energy can be absorbed. At this time, the locking part 2
Since 0 is located on the flange 7 outside the side member 1, the load in the longitudinal direction can be transmitted to the side member 1 by the locking portion 20.

Is formed as an arc having a radius R with the fulcrum as a fulcrum. A partition 43 is provided between the side member fitting portion 4 and the reinforcement fixing portion 5 to separate two closed sections 44 and 45. Further, the reinforcement fixing portion 5 has a closed cross section 45 formed in a triangular shape without the outer wall. The other configuration is the same as that of the first embodiment, and thus the same reference numerals are given and the description is omitted.
