To provide a shock-absorbing mechanism which can exhibit the same buffer characteristics every time against multiple times of shock.SOLUTION: A beam 30 for a landing gear as a shock-absorbing mechanism comprises: a bar-shaped moving part 100 which moves upon receiving shock; a shock absorption member 200 which stops movement of the moving part 100 with a part plastically deformed by being pressed by the moving part 100 when the moving part 100 moves; a moving mechanism part 400 which moves the moving part 100 whose movement is stopped by the shock absorption member 200 so as to cancel at least a part of movement amount of the moving part 100; and a hollow body 500 which guides linear movement of the moving part 100 by receiving one end side of the moving part 100 inside. The beam 30 for the landing gear comprises the shock absorption member 200 and the moving mechanism part 400 so that the same buffer characteristics can be exhibited every time against shock during multiple times of landing.SELECTED DRAWING: Figure 3

    【課題】複数回の衝撃に対して毎回同じ緩衝特性を示すことのできる衝撃緩衝機構を提供する。【解決手段】衝撃緩衝機構である着陸脚用ビーム30は、衝撃を受けて移動する棒形状の移動部100と、移動部100が移動したときに移動部100に押されて一部が塑性変形し移動部100の移動を止める衝撃吸収部材200と、移動部100の少なくとも一部の移動量をキャンセルするように、衝撃吸収部材200により移動を止められている移動部100を移動させる移動機構部400と、移動部100の一方の端部の側を内部で受けて、移動部100の直線的な移動をガイドする中空体500と、を備える。着陸脚用ビーム30は衝撃吸収部材200及び移動機構部400を備えているので、複数回の着陸時における衝撃に対して、毎回同じ緩衝特性を示すことができる。【選択図】図3
