PROBLEM TO BE SOLVED: To provide a vehicle structure embodied light and equipped with a wide internal space. SOLUTION: A roof structural member 20 and a side structural member 40 of this vehicle structure are each formed from a plurality of hollow shapes. The thickness of the hollow shape 240 of the connection part of the roof central part 21 with an eave part 60 is smaller than the thickness of the hollow shape in the other parts. A face plate on the intra-vehicle side of the hollow shape of the roof structural member 20 is curved convex to outside the vehicle. The thickness of the hollow shapes 420 and 430 in the central part 41 of the side structural member 40 is smaller than the thickness of the other hollow shapes of the side structural member 40, and the surface is curved convex to outside the vehicle. Each hollow shape of convex curved surface increases its thickness smoothly toward the adjoining hollow shape. Accordingly even in the case an internal pressure is applied to the vehicle structure, its mass is reduced, and the intra-vehicle space is widened without dropping the structural strength of the structure.
