PROBLEM TO BE SOLVED: To provide a novel and improved energy absorbing structure capable of suppressing a decline in the energy absorption amount of an energy absorbing member when collapsed.SOLUTION: The energy absorbing structure includes a cylindrical fiber reinforced resin energy absorbing member to be collapsed in the axial direction in input of a collision load, to absorb collision energy, and a cylindrical cover member covering an area on the outer peripheral face of the energy absorbing member and adapted to be collapsed in the axial direction by the collision load when input. In the peripheral face of the cover member, a plurality of openings are provided which overlap one another at least in part to communicate the inside of the cover member with the outside in the state that the cover member is collapsed by the collision load.SELECTED DRAWING: Figure 1
【課題】エネルギ吸収部材の圧壊におけるエネルギ吸収量の低下を抑制することが可能な、新規かつ改良されたエネルギ吸収構造体を提供する。【解決手段】衝突荷重の入力時に軸方向に圧壊して衝突エネルギを吸収する繊維強化樹脂製の筒状のエネルギ吸収部材と、前記エネルギ吸収部材の外周面を覆い、前記衝突荷重の入力時に軸方向に圧壊する筒状のカバー部材と、を備え、前記カバー部材の周面には、前記衝突荷重により前記カバー部材が圧壊した状態において、互いに少なくとも部分的に重畳し、前記カバー部材の内部と外部とを連通する複数の開口部が設けられる、エネルギ吸収構造体が提供される。【選択図】図1
