PROBLEM TO BE SOLVED: To improve shock absorption capacity of a shock absorption member, by making a crushed remainder amount of wood at the time of receiving shock load small with a structure having fixed moisture content of wood.SOLUTION: A shock absorption member includes wood 12 and a closed container 20 for housing the wood 12. The shock absorption member 10 is constituted such that the wood 12 and the closed container 20 are crushed by receiving shock load F thereby to absorb the shock load F. At the predetermined position of the closed container 20, provided is a fragile part 25u fractured with the shock member F received through the wood 12.SELECTED DRAWING: Figure 2
【課題】本発明は、木材の含水率を変化させない構造で衝撃荷重を受けたときの木材の潰れ残り量を少なくできるようにして、衝撃吸収部材の衝撃吸収能力を向上させることを目的とする。【解決手段】本発明に係る衝撃吸収部材は、木材12と、その木材12を収納する密閉容器20とを備え、衝撃荷重Fを受けて木材12と密閉容器20とが共に潰れることで衝撃荷重Fを吸収できるように構成された衝撃吸収部材10であって、密閉容器20の所定位置には、木材12を介して受けた衝撃荷重Fにより破断する脆弱部25uが設けられている。【選択図】図2
