To provide a structural member that can exert excellent collision safety performance by improving load resistance at the time of initial stroke and impact absorption energy, in a local buckling mode deformation.SOLUTION: A structural member of an automobile body comprises a hat-shaped member and a joining member, in which a complex bead extending along a longitudinal direction is formed in a top plate part or a top plate opposing part. The complex bead has a pair of bead side walls, a pair of bead bottom walls and a swollen part. The swollen part has, on a cross section perpendicular to the longitudinal direction, has a pair of inclined sites extending so that a separation distance therebetween increases as going outward in a height direction from first end parts and a central site connecting second end parts in the pair of inclined sites to each other.SELECTED DRAWING: Figure 2A

    【課題】局部座屈モードの変形の、ストローク初期における耐荷重と、衝撃吸収エネルギとを向上させることでより優れた衝突安全性能を発揮することが可能な構造部材を提供する。【解決手段】ハット型部材と接合部材と、を備え、天板部又は天板対向部に長手方向に沿って延在する複合ビードが形成され、複合ビードは、一対のビード側壁と一対のビード底壁と膨出部とを有し、長手方向に垂直な断面において膨出部は、第一端部から高さ方向の外方に向かうに連れて互いに離間距離が増大するように延在する一対の傾斜部位と、一対の傾斜部位における第二端部同士を繋ぐ中央部位とを有する自動車車体の構造部材。【選択図】図2A
