To provide a reclining device which enables movement in an eccentric direction between an internal tooth gear and an external tooth gear to the extent that the external tooth gear and the internal tooth gear are surely engaged at the time of lock, and can stabilize slide by bringing the member into contact with a cylindrical boss of a gear with a large area even at the time of slide.SOLUTION: A reclining device 100 includes: an external tooth gear 10; an internal tooth gear 20; a ring 40 which is formed so that a center of an outer peripheral surface formed in a circle and a center of an inner peripheral surface formed in a circle are eccentric, and is formed with a through hole for an elastic body; a rotary shaft 30 having a pressing extension part for pressing the ring 40; a pair of wedge-shaped cams 50 arranged on a back face side of the ring 40; and an elastic body 60 for energizing the pair of wedge-shaped cams 50 through the through hole for the elastic body of the ring 40 so as to separate the pair of wedge-shaped cams 50.SELECTED DRAWING: Figure 3

    【課題】ロック時においては外歯歯車と内歯歯車とが噛合している側が確実に噛合する程度に内歯歯車と外歯歯車との偏心方向の移動が可能であり、摺動時においても部材が歯車の円筒ボスと多くの面積で接することによって、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、円形に形成された外周面の中心と円形に形成された内周面の中心が偏心して形成され、弾性体用貫通孔が形成されているリング40と、リング40を押圧する押圧延設部を有する回転シャフト30と、リング40の背面側に配置され一対のくさび状カム50と、リング40の弾性体用貫通孔を介して、一対のくさび状カム50をそれぞれ離間する方向に付勢する弾性体60と、を備えてなることを特徴とする。【選択図】図3
