Abstract
An impact energy absorber includes: an interaction member and a plurality of energy absorbing members disposed radially around the interaction member, each of the energy absorbing members having a contact portion disposed on the interaction member side for being contactable with the interaction member, a ceiling portion disposed in the radially outside of the interaction member for receiving an impact force, and a shrinkable portion disposed between the contact portion and the ceiling portion so that the shrinkable portion is plastically deformable so as to shrink in the radial direction of the interaction member. The impact energy absorber can make the quantity of absorbed energy constant even if the acting angle of an impact force varies, so that it is possible to improve the degrees of freedom of the installation for the impact energy absorber.
