VEHICLE SKELETON STRUCTURE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To suppress deformation of a cross section when twisting is applied to a vehicle skeleton member by enhancing twisting rigidity of the vehicle skeleton member while suppressing increase of weight of the vehicle.;SOLUTION: The vehicle skeleton structure includes: a rocker 10 (vehicle skeleton member) having a polygonal closed cross section; and a reinforcement member 12 bonded to corner parts 10A, 10B, 10C, 10D respectively in the closed cross section 14 of the rocker 10 by a foaming member 32 (bonding means) extending in a direction of at least two pairs of mutually opposed corner parts 10A, 10B and corner parts 10C, 10D and provided on end parts 12A, 12B, 12C, 12D. In the polygonal closed cross section 14 of the rocker 10, at least two pairs of mutually opposed corner parts 10A, 10B and corner parts 10C, 10D are bonded to each other by the reinforcement member 12 respectively, thereby, twisting rigidity of the rocker 10 is enhanced.;COPYRIGHT: (C)2009,JPO&INPIT
