To provide a seat reclining device which can suppress occurrence of useless processing or shape by forming an inner tooth part on a wall part having a thickness, which is substantially the same as that of a flange part, on a tip inner periphery of a cylindrical part of a driving member.SOLUTION: A driving bush 5, which rotationally drives a pair of wedge members 9 in a circumferential direction in an eccentric space 8, comprises: a cylindrical part 5a which is rotatably supported in a boss part 4d of an inner tooth constitution member 4; a flange part 5b which is integrally provided at one end of the cylindrical part in an axial direction, and is located on one side surface side of both wedge members; and a pressing part 5c which is integrally provided on an outer peripheral side of the flange part, and presses both wedge members from the circumferential direction to release wedge action. A wall part 5f is integrally formed on an inner peripheral surface of the cylindrical part, and a female spline tooth 5g, with which an output shaft of a motor engages, is formed at a center of the wall part. The cylindrical part, the wall part including the female spline tooth and the flange part respectively have the substantially same thickness width.SELECTED DRAWING: Figure 1

    【課題】駆動部材の円筒部の先端部内周にフランジ部とほぼ同じ厚さの壁部に内歯部を形成することによって無駄な加工や形状の発生を抑制し得るシートリクライニング装置を提供する。【解決手段】一対の楔部材9を偏心空間8で円周方向に回転駆動する駆動ブッシュ5は、内歯構成部材4のボス部4dの内部に回転可能の支持される円筒部5aと、円筒部の軸方向の一端部に一体に設けられ、両楔部材の一側面側に配置されたフランジ部5bと、フランジ部の外周側に一体に設けられて、両楔部材を円周方向から押圧して楔作用を解除する押圧部5cと、を備え、円筒部の内周面に壁部5fが一体に形成されていると共に、該壁部の中央にモータの出力軸が噛合する雌スプライン歯5gが形成され、円筒部と雌スプライン歯を含む壁部及びフランジ部のそれぞれの厚さ幅がほぼ同一に形成されている。【選択図】図1
