To provide an impact absorption mechanism that can preferably absorb an impact.SOLUTION: An impact absorption mechanism 2 configured to reduce an impact load applied to a vehicle is provided between a bumper reinforcement 11 that receives an impact load and a side member 9 to which the impact load is transmitted from the bumper reinforcement 11. The impact absorption mechanism 2 includes a wooden columnar impact absorption member 1, a cover member 7 that covers the impact absorption member 1, and a bolt 3. The bolt 3 is connected to the side member 9 and has a flat surface portion 5 and a protruded surface portion 6 that face the bumper reinforcement 11. The bolt extends through a portion of a rear end portion of the impact absorption member 1. At the time of a collision of the vehicle, the flat surface portion 5 of the bolt 3 presses the impact absorption member 1 and the protruded surface portion 6 presses the cover member 7 on the side in an axial direction of the impact absorption member 1.SELECTED DRAWING: Figure 2 【課題】好適に衝撃吸収を行うことのできる衝撃吸収機構を提供する。【解決手段】衝撃吸収機構２は車両に加わる衝突荷重を軽減させるためのものであり、衝突荷重を受けるバンパーリインフォース１１と衝突荷重がバンパーリインフォース１１から伝達されるサイドメンバ９の間に設けられる。衝撃吸収機構２は、木製の柱状の衝撃吸収材１と衝撃吸収材１を覆う被覆材７とボルト３を有する。ボルト３はサイドメンバ９に連結され、バンパーリインフォース１１に面した平面部５と凸面部６を有し、衝撃吸収材１の後端部の一部を貫通する。車両衝突時には、ボルト３の平面部５が衝撃吸収材１を押圧し、凸面部６が衝撃吸収材１の部材軸方向の側面の被覆材７を押し分ける。【選択図】図２
