Abstract: A lower vehicle body structure for a vehicle includes a floor panel, a pair of side frames, a battery, a left and right pair of side sills, a cross-member, an impact absorption member, and a reinforcement member. The impact absorption member is disposed at a lower surface side of the floor panel and at a position overlapping the cross-member in a front-rear direction of the vehicle body so as to extend in a vehicle width direction between the side frames and the side sills. Also, the impact absorption member is joined to the side frames and the side sills. The reinforcement member is disposed in the cross-member to extend in the vehicle width direction between portions of the cross-member, which correspond to the left and right pair of side frames in the vehicle width direction.
