Vehicle structure

Abstract

A vehicle structure includes: a pair of side frames disposed apart in a vehicle width direction and extending in a vehicle front-rear direction; and a cross member extending in the vehicle width direction, and penetrating the pair of side frames and connecting the pair of side frames. The cross member is formed of a pipe having a substantially square cross section with a corner portion curved in an arc shape. A corner portion of the cross member at a vehicle lower side is set to have a curvature radius larger than a curvature radius of a corner portion at a vehicle upper side.
