To provide an automobile structural component which can easily improve collision resistant performance while suppressing weight increase due to reinforcement.SOLUTION: An automobile structural component has a hollow member which constitutes a closed cross-sectional shape in such a manner that opposite flange parts 10C, 11C in two hat cross section members 10, 11 comprising a hat cross-sectional shape, in which side wall parts 10B, 11B and the flange parts are continuous on both sides of top plate parts 10A, 11A respectively. When an opposite direction of two top plate parts is so made as to be a height direction, a position in a height direction of a first mating surface S2 that is a joint area between one flange parts, and a position in a height direction of a second mating surface S1 that is a joint area between the other flange parts are different from each other.SELECTED DRAWING: Figure 2
【課題】補強による重量の増加を抑えつつ、簡便に耐衝突性能を向上させることが可能な自動車用構造部材を提供する。【解決手段】天板部10A、11Aの両側にそれぞれ側壁部10B、11B及びフランジ部10C、11Cが連続する断面ハット形状からなる2つのハット断面部材10、11における、対向するフランジ部同士をそれぞれ接合して閉断面形状を構成する中空部材を有し、2つの天板部の対向する方向を高さ方向とした場合、一方のフランジ部同士の接合面である第1合わせ面S2の高さ方向の位置と、他方のフランジ部同士の接合面である第2合わせ面S1の高さ方向の位置と、が異なる。【選択図】 図2
