PROBLEM TO BE SOLVED: To provide an impact absorption structure body facilitating control over an impact absorption characteristic, capable of reducing variation of such impact absorption characteristic and making a common formation of constituting elements and to provide an impact absorption structure capable of realizing these features effectively.SOLUTION: This invention is constituted in such a way that a plurality of holes are formed at a plate-like body to be spaced apart to each other in a prescribed interval. Each of the plurality of holes is formed with at least one cut-and-raised piece integrally raised up from the hole side edge by a prescribed height. A deformed part is formed with the cut-and-raised piece to have a size giving a planer shape capable of being stored in each of the holes. A plurality of impact absorption plates are overlapped to each other. When an impact energy is inputted to the impact absorption plates, at least one cut-and-raised piece is abutted against the plate-like body of another adjoining impact absorption plate and plastically deformed to cause such impact energy to be absorbed.
【課題】衝撃吸収特性の制御が容易であると共に、かかる衝撃吸収特性のバラツキを少なくすることが出来、しかも構成部品の共通化が可能な衝撃吸収構造体を提供すること、またそれらの特徴を有利に発揮することが出来る衝撃吸収構造を提供すること。【解決手段】板状体に、複数の孔部が互いに所定の間隔を隔てて形成されていると共に、かかる複数の孔部のそれぞれに、孔辺縁部から一体的に所定高さで立ち上がる少なくとも一つの切起し片が、それぞれの孔部内に収容され得る平面形状を与える大きさにおいて形成されてなる変形部を設けて得られる衝撃吸収プレートを用い、その複数枚を相互に重ね合わせて、衝撃エネルギの入力時に、少なくとも一つの切起し片が、隣接する他の衝撃吸収プレートの板状体に当接して塑性変形することにより、かかる衝撃エネルギが吸収せしめられるように構成した。【選択図】図6
