To provide a seat rotating device which can optimally set a standing speed when standing up a seat back.SOLUTION: A seat rotating device comprises: a seat cushion; a seat back; and a support part which so supports the seat back as to be rotatable around an axis L2 within a prescribed range including a standing position from a tilted position that was tilted forward. The support part has a return mechanism 40 for returning the seat back to the standing position, and the return mechanism 40 has: a spiral spring 41 which energizes the seat back positioned at the tilted position in a standing direction; a lock mechanism which holds the seat back at the tilted position against energization force of the spiral spring 41; and a stopper 43 which restricts that energization force of the spiral spring 41 acts on the seat back at a prescribed position between the tilted position and the standing position.SELECTED DRAWING: Figure 8

    【課題】シートバックを起立させる際の起立速度を最適に設定することが可能なシート回動装置を提供する。【解決手段】シート回動装置は、シートクッションと、シートバックと、前方に倒回した倒回位置から起立位置を含む所定範囲内で、軸線L2を中心としてシートバックを回動可能に支持する支持部と、を備える。支持部はシートバックを起立位置に復帰する復帰機構40を有し、復帰機構40は、倒回位置に位置するシートバックを起立方向に付勢する渦巻ばね41と、渦巻ばね41の付勢力に抗してシートバックを倒回位置に保持するロック機構と、倒回位置と起立位置との間の所定位置で、渦巻ばね41の付勢力がシートバックに作用することを制限するストッパ43と、を有する。【選択図】図8
