Abstract: A vehicle floor structure is provided in which a plurality of cross-members are extended between left and right floor frame members at predetermined longitudinal intervals, and a floor panel is mounted to the left and right floor frame members and the crossmembers. A corrugated sheet having a plurality of longitudinally oriented ridges is disposed in a space formed by the left and right floor frame members and the crossmembers. Left and right side portions of the corrugated sheet are connected to the left and right floor frame members. Front and rear edge portions of the corrugated sheet are connected to opposite ones of the crossmembers. If the right floor frame member, for example, is subjected to a load upon an offset collision of the vehicle, the load is transmitted to the left floor frame via the corrugated sheet for dispersion.

Abstract: A vehicle floor structure with a floor body provided to a body frame is provided. The floor body is a hollow panel integrally formed by arranging a plurality of core materials with spaces on a flat plate and placing another flat plate over the core materials. In order to increase the rigidity of the entire floor body, core materials in edge portions of the floor body are joined to the body frame.
