[Operation and Effect] When a load is applied to the bumper cover from the front or diagonally front, the bumper cover escapes rearward and the storage portion of the bumper cover hits the cushion to deform the cushion. This absorbs energy.

Since the energy can be absorbed by the deformation of the cushion, even if the escape stroke of the bumper cover is small, the effect of preventing the damage of the bumper can be enhanced. In other words, by appropriately selecting the spring constant or rigidity of the cushion, the escape stroke of the bumper cover can be reduced.

In the embodiment shown in FIG. 1, the cushion 12
Is located behind a storage chamber 22 for the light source 20 provided in the storage unit 16. On the other hand, the rigid member 32 is formed by the corner portion of the front side member 34, and the radiator support 36 extends from the rigid member 32. In the cushion 12, the stud bolt 38 implanted in the rigid member 32 is inserted into the bolt hole 12 of the cushion,
A nut 40 is screwed into the stud bolt 38 and attached to the rigid member 32. A metal collar (not shown) is embedded in the cushion 12 to form a bolt hole, and the nut 4
It is preferable that the cushion 12 is not deformed even when 0 is screwed in. Furthermore, in the illustrated embodiment, the surface 13 of the cushion 12 facing the storage chamber 22 is

By arranging the cushion 12 on the rigid member 32 formed by the corner portion of the front side member 34 as in this embodiment, the cushion 12 is formed.
It is possible to firmly support. In addition, if the surface 13 of the cushion 12 facing the storage chamber 22 has a shape that matches the shape of the storage chamber 22, the escape stroke of the bumper cover 10 is received by a large area of the cushion 12, and the cushion 12
Can be deformed uniformly, so that the elastic energy of the cushion 12 can be effectively expressed. Furthermore, since the stud bolt 38 implanted in the rigid member 32 is inserted into the bolt hole of the cushion, when the cushion 12 is attached,
There is no need to support the cushion 12 so that it will not fall, and workability is good.

When a load is applied to the bumper placed in use from the front or diagonally front, the bumper cover 10 escapes rearward, and the storage portion 16 compressively deforms the cushion 12. Thereby, the collision energy is absorbed. In this way, since the cushion 12 is deformed and absorbs energy, a short stroke is sufficient according to the present invention A as shown in FIG. 3, whereas the conventional bumper B absorbs the same energy. It required a long stroke.
