A bumper absorber includes an upper leg and a lower leg, each of which extends in a longitudinal direction of an automobile, and a spanning portion. The spanning portion connects the upper leg and the lower leg, and faces an outer surface side of the bumper absorber in a longitudinal direction of the automobile. Each of the upper leg and the lower leg includes a buckling inductive portion that serves as a starting point of the buckling that is caused when the spanning portion receives an impact load. The buckling inductive portion is formed as an angular transition portion in which the angle of inclination between inner side surfaces changes. The inner side surfaces mutually face between the upper leg and the lower leg that include the buckling inductive portion.

It is an object of the present invention to provide a shock absorbing structure for a vehicle that enables a simple and appropriate tuning of a load displacement characteristic, so that a desired amount of collision energy can be absorbed. In the present invention, each of two side walls which is integrally provided with top wall, to which a shock is applied, has a rectangular wave shape corrugated at a plurality of corrugated sections positioned to be opposed to each other in a direction perpendicular to a direction in which the shock is applied. In addition, outer flanges are integrally formed on an end section of each of the side walls, and a slit extending in the direction in which the shock is applied is formed on each of the corrugated sections.
