The vehicle body structure of the invention utilizes ribs to actively absorb impact energy and realize light weight. A vehicle body rear structure (1) according to an embodiment includes a rear floor panel (2, 3) formed of a steel plate having a tensile strength of 440 MPa or more, the rear floor panel (2, 3) having ribs (13, 23) extending in a predetermined direction throughout the entire surface, and the direction in which the ribs (13, 23) extend and the type of the ribs (13, 23) are set so as to reduce the difference between a peak load and an average load during a collision.
本发明的车体结构利用筋来积极地吸收冲击能量且实现轻量化。实施方式的车体后部结构(1)包括:后地板面板(2、3),由具有440MPa以上的拉伸强度的钢板所形成,后地板面板(2、3)遍及整个面具有沿规定方向延伸的筋(13、23),筋(13、23)延伸的方向及筋(13、23)的种类是以缩小碰撞时的峰值负荷与平均负荷之差的方式设定。
