がある。2. Description of the Related Art A conventional bumper mounting structure for a vehicle employs a structure in which a bumper beam and a bumper stay are sub-assembled in advance on a bumper face and mounted on a vehicle body (Japanese Patent Laid-Open No. 6-227333). Since the weight of the sub-assembled bumper increases, one worker holds the sub-assembly and the other worker works to fix it to the body frame with bolts or the like. There is. In addition, the bumper stay has ribs or vertical walls that are offset from the vertical walls of the vehicle body frame, so the impact load at the time of collision is transmitted to the vehicle body frame as an out-of-plane load, and the collision energy is absorbed. There is a problem in the point.

作業性も向上する。For this reason, a bumper mounting structure has been proposed which has good mounting workability and can efficiently absorb collision energy (JP-A-9-86309, JP-A-9-86309).
No. 1-208392). The bumper mounting structure of Japanese Patent Application Laid-Open No. 9-86309 will be described with reference to FIG. 5. FIG. 5 is a side sectional view, in which 101 is a bumper beam formed from a light alloy such as an aluminum alloy, 101a is a bumper face, 1
02 is a bumper stay formed from a light alloy such as an aluminum alloy, and 103 is a vehicle body frame. This bumper mounting structure includes a bumper stay 102 formed by extrusion of light metal, a box-shaped main body 102a, and a bumper beam 10.
1 and a fitting portion 102c fitted into the vehicle body frame 103. The fitting portion 102c is fitted into the body frame 103, and the vehicle body frame 103 and the fitting portion 102c are fitted. At the same time, the bolt 104 is passed therethrough, and the nut 104 is tightened and fixed. With this configuration, the protruding portion 102b and the main body portion 102a of the bumper stay 102 are crushed at the time of a collision, so that energy is absorbed in the initial stage of the collision, and the mounting portion by the bolt 104 does not prevent the buckling of the vehicle body frame 103.
The vehicle body frame 103 forward (left side in the figure) of the vehicle body 4 is buckled and deformed in a well-balanced manner, the effective crash stroke is increased, and the collision energy is effectively absorbed. In addition, the overall weight is reduced because the bumper beam and bump paste are molded using a light alloy or the like,
Workability is also improved.

Portion), and the fitting portion behind the bolted position does not contribute to shock absorption, so there is room for improvement in the impact absorption efficiency of the bumper stay. Further, when the vehicle body frame is bolted to the fitting portion, the longitudinal load input is transmitted to the vehicle body frame via the bolt, so that the load is concentrated at this portion and the vehicle body frame is deformed. Therefore, there is room for improvement in transmission efficiency. Further, even in the latter structure, the portion that contributes to absorbing the impact of the fitted portion is located forward of the bolt portion 204 (left portion of the bolt in the drawing), and is not contributed behind the bolted position. Therefore, there is room for improvement in the impact absorption efficiency of the bumper stay.

The entire fitting portion of the bumper stay fitted in the cross section of the body frame can function as a shock absorber, and the drag of the whole body frame can be improved.
Further, since the bumper stay is surface-coupled to the vehicle body, it can surely receive a load, and also has improved torsional rigidity. By using the existing bracket for attaching the cross member as reinforcement, the number of parts can be reduced. By providing reinforcing ribs in the cross section of the bumper stay, the strength of the bumper stay can be improved, and by making the reinforcing rib the same straight line as the side wall of the body frame, the collision load can be directly transmitted from the reinforcing rib to the body frame. Can be transmitted. In addition, excellent effects such as a simplified structure as a whole and an improvement in mounting work can be obtained.
