To maintain or improve energy absorption performance when vehicles are collided while reducing weight in a vehicle structural member.SOLUTION: A vehicle structural member 1 has a metal hollow member 10 and a reinforcement member 20 which is bonded to an inner surface of the hollow member 10 and continuously formed along a member longitudinal direction X of the hollow member 10. When in a coordinate axis with a center of gravity O of a cross section vertical to the member longitudinal direction X of the hollow member 10 as an original point, a main axis where a cross section secondary moment becomes maximum is called a first axis Aand an axis in the direction vertical to the first axis Ais called a second axis A, the reinforcement member 20 is provided in one of two regions R, Rof the hollow member 10 divided with the second axis Aas a boundary.SELECTED DRAWING: Figure 5

    【課題】車両用構造部材において、軽量化を図りつつ、車両衝突時のエネルギー吸収性能を維持または向上させる。【解決手段】金属製の中空部材10と、中空部材10に接合された、中空部材10の部材長手方向Xに沿って連続的に形成されている補強部材20とを有し、中空部材10の部材長手方向Xに垂直な断面の重心Oを原点とした座標軸において、断面2次モーメントが最大となる主軸を第1軸A1と称し、第1軸A1に垂直な方向の軸を第2軸A2と称したとすると、補強部材20は、第2軸A2を境界として分割された中空部材10の2つの領域R1、R2のうちのいずれか一方の領域に設けられるように車両用構成部材1を構成する。【選択図】図5
