Vehicle structure

A vehicle structure comprising a structural body, in which a pair of wheel houses disposed apart from each other in a right-left direction, and a floor panel connecting the pair of wheel houses are integrally formed by die casting, wherein

• the floor panel includes a frame connection portion, to which an inboard end portion of a frame extending along a front-rear direction of a vehicle is connected,
• each of the wheel houses is shaped like a shell and includes:
• a concave surface portion that faces outward in a vehicle width direction and is formed of a concave curved surface curved in a substantially spherical shape, and
• a convex surface portion that is formed on a back side of the concave surface portion, protrudes inward in the vehicle width direction, and is formed of a convex curved surface curved in a substantially spherical shape,
• the concave surface portion is disposed so as to face outward in the vehicle width direction, and a part of a wheel is housed in the concave surface portion, and
• the concave surface portion has a horizontal rib that extends along a horizontal plane and rises toward an outer side in the vehicle width direction.
