To provide an impact absorption mechanism or the like which can suitably absorb an impact.SOLUTION: An impact absorption mechanism 5 comprises an impact absorption part 7 for alleviating an impact load A applied on a vehicle, and composed of a lumber, and a pair of constriction members 9 which are arranged so as to sandwich the impact absorption part 7 toward the inside in a vertical direction. The pair of constriction members 9 are connected to each other at only both end parts of the impact absorption part 7 in a longitudinal direction with the impact absorption part 7 sandwiched therebetween, and designed such that a value of a thickness tw (mm) of the impact absorption part 7 and values of thicknesses tm (mm) of the constriction members 9 satisfy 0.33≤0.0147 tw+0.0458 tm2≤2.SELECTED DRAWING: Figure 4
【課題】好適に衝撃吸収を行うことのできる衝撃吸収機構等を提供する。【解決手段】衝撃吸収機構5は、車両に加わる衝突荷重Aを軽減するためのものであり、木材からなる衝撃吸収部7と、鉛直方向において衝撃吸収部7を内側に挟み込むように配置される一対の拘束部材9と、を具備する。一対の拘束部材9は、衝撃吸収部7の長手方向の両端部のみで、衝撃吸収部7を挟んで連結され、衝撃吸収部7の厚さtw(mm)の値と、拘束部材9の厚さtm(mm)の値が、0.33≦0.0147tw+0.0458tm2≦2を満たすように設計される。【選択図】図4
