An outer reinforcement panel supports a toe board which connects a front frame and a floor panel from the undersurface of the toe board and an inner reinforcement panel supports the toe board from the topsurface of the toe board. On the outer reinforcement panel, three frames having U-shaped cross sections are integrally formed with the outer reinforcement panel in a radial manner and these frames are welded at the ends thereof to primary body skeletons such as a side sill, a wheel house, a side frame and the like. Similarly, on the inner reinforcement panel, two frames having inverse U-shaped cross sections are integrally formed with the inner reinforcement panel in a radial manner and these frames are also welded at the ends thereof to those primary body skeletons. Thus, a plurality of frames having closed cross sections are formed on inner and outer surfaces of the toe board and the floor panel. Even in the event of an offset collision or an oblique collision, since an impact energy is transmitted well diffusively to these body skeletons through these frames, the damage to passengers can be minimized. <IMAGE> <IMAGE> |
