To provide an impact energy absorption device which can suppress a peak load occurring at an initial stage of a collision to avoid reduction of the load immediately after the initial stage.SOLUTION: An impact energy absorption device 10 is attached to a vehicle, absorbs impact energy, and includes: a compression member 30; an absorption member 40; and a guide part 21c which guides a moving direction of the compression member. The absorption member is provided with a hole 43 into which the compression member guided by the guide part moves. During a collision, the compression member is guided by the guide member and moves into the hole with a tip part of the compression member shearing an inner wall of the hole formed at the absorption member to absorb impact energy.SELECTED DRAWING: Figure 3
【課題】衝突初期のピーク荷重とその直後の荷重落ち込みを抑制することができる衝突エネルギ吸収装置を提供する。【解決手段】車両に取り付けられ、衝突エネルギを吸収する衝突エネルギ吸収装置10であって、加圧部材30、吸収部材40及び前記加圧部材の移動方向をガイドするガイド部21cを備え、前記吸収部材には、前記ガイド部にガイドされて移動する前記加圧部材が進入する穴43が形成されており、衝突時、前記加圧部材は、前記ガイド部によりガイドされ、当該加圧部材の先端部が前記吸収部材に形成された前記穴の内壁をせん断しつつ前記穴に進入することにより衝突エネルギを吸収する。【選択図】図3
