PROBLEM TO BE SOLVED: To provide a vehicle lower body structure which can suppress the movement of a spare tire to a front upper part while securing collision energy absorption performance at a rear collision.SOLUTION: A vehicle lower body structure comprises: a pair of left and right side sills 1 which extend to a fore-and-aft direction; a floor panel 2 which is laid on the pair of side sills 1; a pair of left and right rear side frames 3 which extend to the fore-and-aft direction at the inside of the pair of side sills 1, and at a lower face side of the floor panel 2; an intermediate cross member 12 and a No.4 cross member 13 which are installed at the pair of rear side frames 3 at the lower face side of the floor panel 2; and a spare tire pan 2a which is formed so as to be recessed downward of the floor panel 2 at a rear side rather than the No.4 cross member 13. The intermediate cross member 12 and the No.4 cross member 13 are connected to each other in the fore-and-aft direction, and a vertical member 4 is arranged in a vehicle width position corresponding to a front end of the spare tire pan 2a.SELECTED DRAWING: Figure 5 |
