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 in two hat cross section members are joined to each other. In the hollow member, 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 that is a joint area between one flange parts, and a position in a height direction of a second mating surface that is a joint area between the other flange parts are different from each other. Further, the automobile structural component comprises: a pair of plates which contacts an outer wall surface of a side wall part on one hat cross member constituting one wall part of the hollow member and an outer wall surface of a side wall part on the other hat cross section member constituting the other wall part of the hollow member respectively; and a connection member which connects the pair of plates, and suppresses increase in a distance between the pair of plates.SELECTED DRAWING: Figure 3
【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】2つのハット断面部材における、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、中空部材は、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合わせ面の高さ方向の位置と、が異なり、更に、中空部材の一方の壁部を構成する一方のハット断面部材側の側壁部の外壁面、及び、中空部材の他方の壁部を構成する他方のハット断面部材側の側壁部の外壁面に、それぞれ当接する一対の板材と、一対の板材を連結して一対の板材間の距離が広がることを拘束する連結部材と、を備える。【選択図】 図3
