To provide a reclining device configured to enable a bush to bear over the whole circumference and to enable the bush to receive even external force from any direction of all directions (360 degrees) so that sliding thereof can be stabilized.SOLUTION: A reclining device 100 comprises: an external tooth gear 10; an internal tooth gear 20; a rotary shaft 30 that is inserted through a cylindrical boss 22 of the internal tooth gear 20 concentrically and rotatably and rotates one of the external tooth gear 10 and the internal tooth gear 20 with the other tooth gear as a center; a bush 40 that has a cam storage part 44 at an inner periphery side and rotates together with rotation of the rotary shaft 30; a pair of a wedge-shaped cams 50; and a spring 60 that energizes the pair of wedge-shaped cams so that the cams contact the bush and the cylindrical boss simultaneously. A gap between a through-hole of the external tooth gear 10 and the bush 40 is larger than a gap between the cylindrical boss of the internal tooth gear and the bush.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】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20の円筒ボス22に同軸かつ回転自在に嵌挿されるとともに、外歯歯車10又は内歯歯車20のいずれか一方を他方の歯車軸を中心に回転させる回転シャフト30と、内周側にカム収容部44を有し、かつ回転シャフト30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スプリング60と、を備え、外歯歯車10の貫通孔とブッシュ40との隙間は、内歯歯車の円筒ボスとブッシュとの隙間よりも大きいことを特徴とする。【選択図】図2
