Vehicle lower structure

Abstract

To increase mounting capacity of a battery while ensuring an energy absorptive function during a side collision, a vehicle lower structure includes a side sill that has a closed cross-section located in a side end portion of a floor panel in a vehicle width direction and extending in a vehicle front-rear direction; a battery casing that is located under the floor panel and has a battery accommodated in an accommodation space; and a fastening portion that fastens the battery casing to a lower portion of the side sill. The fastening portion is located at a position that overlaps a cross-sectional center of the side sill in the vehicle width direction, or is located on an outer side of the cross-sectional center in the vehicle width direction.
