This vehicle strength member is provided with a top plate and a pair of vertical walls, and is formed in a hat-shaped cross-section. In addition, the vehicle strength member is provided with a plurality of bent portions in the long-side direction, the bent portions being formed by bending the bent lines extending in the short-side direction, and the vehicle strength member is bent as a whole. The top plate has a recess extending in the longitudinal direction in the center thereof, and a pair of ridges extending in the longitudinal direction on both sides of the recess. In addition, the top plate is provided with at least one convex rib extending along the short side direction at a position corresponding to each bent part in the concave part, and two ends of the convex rib are combined with the side part of the protruding strip.
本发明的车辆用强度部件具备顶板和一对纵壁,并且形成为剖面呈帽形状。另外,车辆用强度部件在长边方向上具备多个通过在短边方向上延伸的弯折线屈曲而成的弯折部,从而整体上弯曲。上述顶板具有在中央沿着上述长边方向延伸的凹部、和在该凹部的两侧沿着上述长边方向延伸的一对突条。另外,上述顶板具备在上述凹部内的与上述各弯折部对应的位置沿着上述短边方向延伸的至少一个凸加强筋,该凸加强筋的两端与上述突条的侧部结合。
