Abstract
A bumper reinforcement member 1 includes a small groove 2 and a large groove 3. The large groove 3 is arranged to encompass the small groove 2 inside the groove. When the bumper reinforcement member 1 is deformed, directions of the deformation of the lateral face of the small groove and the deformation of the lateral face of the large groove are oppose to each other, and thus the peak load and the energy absorption amount of the bumper reinforcement member 1 can be increased with a simple configuration.
