SHOCK ABSORBING MEMBER, VEHICLE BODY, AND SHOCK ABSORBING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a shock absorbing member that has collision energy absorbing function regardless of the input direction of collision load during collision even if a super-high tensile steel plate with a tensile strength of 980 MPa or greater is used as a material and that is able to be stably bent in an N-shape in a plane view.SOLUTION: A shock absorbing member comprises a press molded body made of high tensile steel plate with a tensile strength of 980 MPa or greater, and absorbs collision load applied in an axial direction. The press molded body has: a top plate 11 having two first ridge lines 12-1a and 12-1b; two second ridge lines 12-2a and 12-2b; two vertical walls 13a and 13b; two recessed ridge lines 14a and 14b; and two outward flanges 15a and 15b. Recessed parts 16 and 17 reaching the vertical walls 13a and 13b from the second ridge lines 12-2a and 12-2b and substantially orthogonal to an axial line are provided in at least two places separated in the respective axial directions of the two vertical walls 13a and 13b.SELECTED DRAWING: Figure 1
