PROBLEM TO BE SOLVED: To provide an energy absorbing structure capable of actualizing its stable load characteristics given by a fiber reinforced resin energy absorbing member by constraining the energy absorbing member destroyed in an outward winding manner, while using a cover for improving chipping-proofness and weather-proofness.SOLUTION: The energy absorbing structure includes the cylindrical fiber reinforced resin energy absorbing member to be collapsed in the axial direction by a load when input, to absorb collision energy, a cylindrical cover body part covering an area on the outer peripheral face of the energy absorbing member, a cylindrical connection cover part connected to the end on the load input side of the cover body part and fixed to a bumper beam of a vehicle or to a member fixed to the bumper beam, and a connection part connecting the cover body part and the connection cover part. The connection part is deformed by the load when input, and then the connection cover part and the front end of the cover body part overlap each other in the peripheral direction.SELECTED DRAWING: Figure 1

    【課題】カバーによって耐チッピング性や耐候性を向上させるとともに、外巻きに破壊された繊維強化樹脂製のエネルギ吸収部材を拘束して、エネルギ吸収部材による安定的な荷重特性を実現可能なエネルギ吸収構造体を提供する。【解決手段】エネルギ吸収構造体は、荷重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、エネルギ吸収部材の外周を覆う筒状のカバー本体部と、カバー本体部における荷重入力側の端部に連結されて車両のバンパビーム又はバンパビームに固定された部材に固定された筒状の接続カバー部と、カバー本体部と接続カバー部とを接続する連結部と、を備え、荷重入力時に、連結部が変形して、接続カバー部とカバー本体部の先端部とが周方向に重なる。【選択図】図1
