To provide a bumper device which can maintain a state that a bumper body side member can move.SOLUTION: A bumper device includes a base side member 2, a bumper body side member 3, and an expansion mechanism part 5. The expansion mechanism part has two front arms 60, 61, two rear arms 65, 66, and connection links 67, 68. Each member forming the expansion mechanism part changes its posture in conjunction with movement of the bumper body side member. The bumper device has a restriction member 6 which restricts movement of the bumper body side member. When the restriction member is in a predetermined restriction posture, the restriction member prevents posture change of the member forming the expansion mechanism part to prevent movement of the bumper body side member. When the restriction member is in an expansible posture, movement of the bumper body side member is allowed. An engagement part engages with another member to fix a rotary shaft at an expansible angle.SELECTED DRAWING: Figure 1

    【課題】バンパー本体側部材を移動させることができる状態を維持することができるバンパー装置を提供する。【解決手段】基部側部材2と、バンパー本体側部材3と、伸縮機構部5とを備え、伸縮機構部は、2本のフロントアーム60、61と、2本のリアアーム65、66と、連結リンク67、68とを有し、伸縮機構部を構成する各部材は、バンパー本体側部材の移動と連動して姿勢変更するものであり、バンパー本体側部材の移動を規制する規制部材6を有し、規制部材が所定の規制姿勢であるとき、伸縮機構部を構成する部材の姿勢変更を阻害してバンパー本体側部材の移動を阻止し、規制部材が伸縮可能姿勢であるとき、バンパー本体側部材の移動が可能となり、係合部が他の部材と係合して前記回動軸を前記伸縮可能角度に固定することが可能であることを特徴とするバンパー装置。【選択図】図1
