PROBLEM TO BE SOLVED: To obtain a vehicle lower part structure which can effectively transmit a collison load to a rear side of a vehicle longitudinal direction or an opposite side of a vehicle width direction on a collison side during a fine lap collision and an oblique collision of a vehicle.SOLUTION: A reinforcement member 36 provided in a front part of a floor panel 14 is obliquely disposed toward an inside of a vehicle width direction as approaching a rear side of a vehicle longitudinal direction from a position (an input part 40) on an outside of the vehicle width direction of and a front side of the vehicle longitudinal direction of the floor panel 14. An outer end part of the reinforcement member 36 is joined to a rocker 18, and an inner end part is joined to a floor tunnel part 16. During a head-on collision of a vehicle, a collision load F of an oblique direction is input to the position on the outside of the vehicle width direction and the front side of the vehicle longitudinal direction of the floor panel 14. By blocking a space between the input part 40 and floor tunnel part 16 with the reinforcement member 36, it is possible to effectively transmit the collision load F, which is input to the input part 40, to the floor tunnel part 16 through the reinforcement member 36. |
