Abstract
A member for a car body in which concave and convex beads can be positioned appropriately regardless of a complexity of a shape of the member, and the efficiency of energy absorption can be improved. The member includes side faces having concave beads provided on the side faces at positions corresponding to dip portions of a buckling waveform produced by an initial buckling load applied to the member in a state of having no bead; convex beads provided on the side faces at positions corresponding to peak portions of the buckling waveform; and flat portions without any bead, formed between each adjacent concave bead and convex bead. The side faces may also have edge beads provided on edges of the side faces at positions corresponding to a dip portion of the buckling waveform which is closest to a front end to be subjected to a crushing load.
