IMPACT ABSORBING STRUCTURE OF VEHICULAR PART HAVING CURVED SURFACE

摘要

PROBLEM TO BE SOLVED: To provide a structure capable of sufficiently and efficiently absorbing an impact from outside applied to a curved surface in a vehicular part having a curved surface such as a curvature surface, a cylindrical surface, or a spherical surface. SOLUTION: An impact absorbing structure body 10 is comprised by integrally erecting a plurality of a flat first rib 14a (16a) and a second rib 14b (16b) on both faces of a substrate 12 in a state combined so as to mutually cross or form a perpendicular corner part. It is constituted so that a tip 32 of at least either of the first or second rib 14a or 14b erected on the face of the substrate 12 is arranged in a state contacting the curved surface 32 of the vehicular part 24 or facing it with an interval in between for transmitting the impact from outside to the curved face 23 of the vehicular part 24 via the impact absorbing structure body 10.
