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 rotates one of the external tooth gear 10 and the internal tooth gear 20 with the other tooth gear as a center; and a bush 40 arranged between an inner periphery of a through-hole 12 of the external tooth gear 10 and an outer periphery of a cylindrical boss 22 of the internal tooth gear 20 and formed into a first bush 41 and a second bush 42. The first bush 41 is formed so that a front-side bush 41a formed in a taper shape so that a tip side thereof is tapered and a back-side bush 41b overlap with each other, whose end part at one side is energized to extend the front-side bush 41a and whose end part at the other side is energized to extend the back-side bush 41b.SELECTED DRAWING: Figure 3

    【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、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ための回転シャフト30と、外歯歯車10の貫通孔12の内周と内歯歯車20の円筒ボス22の外周との間に配置され、第1ブッシュ41と第2ブッシュ42とに分割して形成されるブッシュ40と、を備え、第1ブッシュ41は、先端側が細くなるようにテーパーが形成された正面側ブッシュ41aと、背面側ブッシュ41bとが重ね合わされて形成されており、一方側端部は正面側ブッシュ41aが延出し、他方側端部は背面側ブッシュ41bが延出されるように付勢されてなることを特徴とする。【選択図】図3
