To provide a reclining device which enables a bush to borne over the whole circumference, and can stabilize slide by receiving force with the bush even when the force is an external force from any direction of 360° .SOLUTION: A reclining device 100 includes: an external tooth gear 10; an internal tooth gear 20; a rotary shaft 30 which is coaxially and rotatably fit and inserted into a boss of the internal tooth gear; the bush 40 which has a cam storage part on its inner peripheral side and is rotated accompanying rotation of the rotary shaft; a pair of wedge-shaped cams 50; and an elastic body for energizing the pair of wedge-shaped cams to a side where the cams are simultaneously brought into contact with the bush and the cylindrical boss, wherein the whole of the cam storage part 44 and the wedge-shaped cams 50 is arranged on a side opposite to a press direction rather than a normal line at the center of the rotary shaft 50 with respect to the engagement direction of each tooth of the internal tooth gear 20 and the external tooth gear 10.SELECTED DRAWING: Figure 2

    【課題】ブッシュが全周に渡って軸受することができるようにし、360°のいずれの方向からの外力であってもブッシュによって力を受けることで摺動を安定化させることができるリクライニング装置を提供する。【解決手段】本発明のリクライニング装置100は、外歯歯車10と、内歯歯車20と、内歯歯車のボスに同軸かつ回転自在に嵌挿される回転シャフト30と、内周側にカム収容部を有し、かつ回転シャフトの回転に伴い回転するブッシュ40と、一対のくさび状カム50と、一対のくさび状カムをブッシュ及び円筒ボスに同時に接触させる方に付勢する弾性体と、を備え、カム収容部44及びくさび状カム50の全体が、内歯歯車20と外歯歯車10の各歯の噛合方向に対して、回転シャフト50の中心における法線よりも押圧方向と反対側に配置されていることを特徴とする。【選択図】図2
