To provide a reclining device capable of filling, with an elastic body, a gap generated by eccentricity between an external tooth gearwheel and an internal tooth gearwheel, by a wedge-shaped cam added to a reclining device, for receiving a load from a gap side.SOLUTION: A reclining device comprises: an external tooth gearwheel 10; an internal tooth gearwheel 20; a ring 30 which is formed in an annular shape by a pair of ring pieces, has a wedge-shaped cam storage part and an elastic member storage part on an inner peripheral surface side, and has a protrusion part on a front surface side; a pair of wedge-shaped cams 50 which allows relative rotation of the external tooth gearwheel and the internal tooth gearwheel; an energization member 70 for energizing the wedge-shaped cams in directions where they separate from each other; an elastic member 75 whose end is inserted into the elastic member storage part, and which has a function as a wedge; a drive member 60; and a rotary shaft 40 which is fitted to the drive member and rotates the ring through the drive member.SELECTED DRAWING: Figure 3

    【課題】リクライニング装置に加わるくさび状カムによって、外歯歯車と内歯歯車による偏心で発生する隙間を弾性体で埋めることで、隙間側からの荷重を受け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は、外歯歯車10と、内歯歯車20と、一対のリング片によって環状に形成され、内周面側にくさび状カム収容部及び弾性部材収容部を有し、正面側に突起部を有するリング30と、外歯歯車と内歯歯車の相対回転を許容する一対のくさび状カム50と、くさび状カムを離間する方向に付勢する付勢部材70と、弾性部材収容部内に端部が挿入され、くさびとしての機能を有する弾性部材75と、駆動部材60と、駆動部材に嵌合して駆動部材を介してリングを回転させる回転シャフト40と、を備えたことを特徴とする。【選択図】図3
