Vehicle lower structure

Abstract

A vehicle lower structure increases mounting capacity of a battery while ensuring an energy absorptive function during a side collision. The vehicle lower structure includes a side sill located in a side end portion of a floor panel in a vehicle width direction and extending in a vehicle front-rear direction; and a battery casing that is located under the floor panel and accommodates a battery. The battery casing has a frame that is located on an outer edge portion of the battery casing in the vehicle width direction, extends in the vehicle front-rear direction, and forms an accommodation space for the battery on an inner side in the vehicle width direction. The frame is fastened to a lower portion of the side sill. The entire side sill overlaps the frame in the vehicle width direction.
