PROBLEM TO BE SOLVED: To support a collision load inputted from a front side frame surely while suppressing weight increase of a dash panel lower to a minimum.SOLUTION: A front side frame 13 includes: lateral plate parts 13d, 13e which smoothly continue to a front end of an inclined wall part 12b of a dash panel lower 12 in a side view; and an outside vertical plate part 13b which smoothly continues to a front end of a wheel arch part 12c of the dash panel lower 12 in a plan view. Thus, since a collision load inputted to the front side frame 13 due to a head-on collision is efficiently transmitted to the high intensity inclined wall part 12b and the wheel arch part 12c of the dash panel lower 12 via the lateral plate parts 13d, 13e and the outside vertical plate part 13b, intensity with respect to the collision load of the head-on collision can be secured, while achieving reduction in weight of a cabin 11 by reducing plate thickness of the dash panel lower 12. |
