PROBLEM TO BE SOLVED: To improve impact energy absorption performance to a side face collision load.SOLUTION: When a side face collision load F is applied, first a left side frame 14 is collapsed, and following to collapse of the left side frame 14, a bent part 22 of a cross member 16 which is bent in a crank-shape is buckled in a Z-shape, thereby excellent impact energy absorption performance is obtained by deformation of them. Especially, collapse of the left side frame 14 and buckling of the cross member 16 are different each other in a deformation state, so that, by adjusting (tuning) deformation intensity of them, the impact energy can be efficiently absorbed with a relatively short deformation stroke.SELECTED DRAWING: Figure 3 |
