PROBLEM TO BE SOLVED: To achieve a vehicle lower part structure capable of further suppressing deformation of a vehicle body at the time of a fine lap collision.SOLUTION: The vehicle lower part structure includes: a front side member coupled to a floor frame 20; a rocker 34 extending in a vehicle longitudinal direction and whose cross section orthogonal to the vehicle longitudinal direction is a closed cross section; a rocker inner 36 constituting the vehicle width direction inner part of the rocker 34; a rocker outer 38 constituting the vehicle width direction outer part of the rocker 34; a connection member 32 connecting the floor frame and the rocker inner 36; a cross member 44 extending in the vehicle width direction from the rocker 34; a front pillar inner 26 whose lower back end 30 is positioned at the back side of the vehicle longitudinal direction of the connection member 32; and a rocker inner reinforce 46 whose front end 52 is positioned at the front side of the connection member 32, and whose back end 54 is positioned at the front side of the vehicle longitudinal direction of the cross member 44 and at the back side of the vehicle longitudinal direction of the back end 30 of the front pillar inner 26.SELECTED DRAWING: Figure 2 |
