An absorber (10) is a hollow structure that extends in a direction in which impact load acts and includes an inner plate (14) of polygonal cross section, an outer plate (12) of polygonal cross section, and a plurality of ribs (16) connecting the inner and outer plates along the direction in which the impact load acts. An outer plate (22) of a front member (20) of polygonal cross section is mounted in front of the absorber (10) to be substantially coaxial with the absorber (10). When viewed in the direction in which the impact load acts, the outer plate (22) of the front member (20) and the inner plate (14) of the absorber (10) are disposed to cross each other. When impact force is applied to the front member (20), prior to crushing of the absorber (12), the front member (20) experiences, while maintaining its central axis along the direction in which the impact load acts, crushing that penetrates into an inner part of the inner plate (14) from where the outer plate (22) and the inner plate (14) cross each other for causing the impact force to act on the inner plate in a radial direction from its central axis. In this way, the load is prevented from acting on a whole surface of the absorber at a time in a collision, whereby a crushing peak load can be lowered, and the impact shock can be relieved.
