PROBLEM TO BE SOLVED: To provide a vehicle structural member with high shock absorption capacity which suppresses breakage and crack of a junction part caused by member deformation in collision.SOLUTION: A vehicle structural member includes a first member 1 which is formed of a first steel plate and has a hat-like cross sectional shape, and a second member 2 which is formed of a second steel plate and is arranged along the first member 1 so as to close an opening part of the first member 1. The vehicle structural member has a closed cross sectional shape by having a junction part which joins a flange part 1C of the first member 1 and a width-direction end part 2A of the second member 2. Tensile strength of the first steel plate is higher than that of the second steel plate. A junction structure of the junction part is a hemming part in which the width-direction end part 2A of the second member 2 is folded, and the flange part 1C of the first member 1 is held by the folded part 2C. The flange part 1C and an inner surface of the folded part 2C are adhered with an adhesive 3 in the folded part 2C.SELECTED DRAWING: Figure 1

    【課題】衝突時の際の部材変形に起因する接合部の破断や割れを抑制した衝撃吸収能の高い車両用構造部材を提供する。【解決手段】車両用構造部材は、第1の鋼板からなり且つハット形断面形状の第1の部材1と、第2の鋼板からなり第1の部材1の開口部を塞ぐように第1の部材1に沿って配置される第2の部材2とを備える。第1の部材1のフランジ部1Cと第2の部材2の幅方向端部2Aとを接合する接合部を有することで閉断面形状となっている車両用構造部材であって、第1の鋼板の引張強度は、第2の鋼板の引張強度よりも高く、接合部の接合構造を、第2の部材2の幅方向端部2Aを折り曲げ、その折り曲げ部2Cで、第1の部材1のフランジ部1Cを挟み込むヘミング加工部とし、且つ、折り曲げ部2C内においてフランジ部1Cと折り曲げ部2C内面とを接着剤3で接着させた構造とした。【選択図】図1
