To provide a shock absorption mechanism which can perform impact absorption favorably.SOLUTION: A shock absorption mechanism 2 is configured so as to reduce buffer load applied on a vehicle and is provided between a bumper reinforcement 11 applying the buffer load and a side member 9 to which the buffer load is transmitted from the bumper reinforcement 11. The shock absorption mechanism 2 includes a columnar impact absorption material 1 made of wood and a bolt 3. A side face of the impact absorption material 1 is coated and its rear end part is inserted into an internal space of a tubular portion of the side member 9. The bolt 3 is connected to the side member 9 and is disposed so as to traverse the internal space of the side member 9 behind the impact absorption material 1. A notch 7 in a direction perpendicularly intersecting with a member axial direction of the impact absorption material 1 is provided on a coating 1a of a face perpendicularly intersecting with a traverse direction of the bolt 3 of a side face of the impact absorption material 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とボルト3とを有する。衝撃吸収材1の側面は被覆され、その後端部はサイドメンバ9の筒状部分の内部空間に挿入される。ボルト3はサイドメンバ9に連結され、衝撃吸収材1の後方でサイドメンバ9の内部空間を横断するように配置される。衝撃吸収材1の側面のうちボルト3の横断方向に直交する面の被覆1aには、衝撃吸収材1の部材軸方向と直交する方向の切込み7が設けられる。【選択図】図2
