Abstract
A main body of an impact energy absorber is formed by integrally molding a deformable portion and a plurality of deformation controlling portions which are adapted to control the direction of plastic deformation of the deformable portion. The deformation controlling portions have such a configuration and shape that, when a compression load equal to or greater than a predetermined value is input to the main body in a tube axis direction, the deformable portion undergoes plastic deformation in at least one of a radially outward direction and a radially inward direction of the main body concurrently with the compressive plastic deformation in the tube axis direction.
