Abstract
A bumper includes a pair of hollow crash boxes, each of which is located at one end of a bumper reinforce. when receiving axial load, each crash box is plastically deformed to absorb the axial load. An initial buckling portion is previously formed in each crash box. Plastic deformation of each crash box due to axial load starts at the associated initial buckling portion. This reduces axial load that is needed to start plastic deformation of each crash box.
