The present invention relates to a dial recliner comprising: a holder having inner teeth at its outer circular part and a boss at its center part; a sector gear having outer teeth to intermesh with the inner teeth for the sector gear to roll in the holder, and a circular receiving part which has a center eccentric from that of the boss and surrounds the boss; a brake spring elastically held around the boss and having a pair of protruding ends which are circularly separated therebetween; a bearing inserted in the receiving part of the sector gear and receiving therein the boss whose center is eccentric from that of the bearing; a cam having a center shaft part which is inserted into the boss, an operating cam part which adjoins an inner surface of the bearing and a spring operating part which is interposed between a pair of the protruding ends of the brake spring; and a pair of clutch shoes interposed between the brake spring and the bearing and also interposed between the operating cam part and one of the protruding ends. Therefore, a structure of the dial recliner is simplified with a small number of components, especially a phenomenon that the seatback is turned back gradually in use can be prevented by removing a drifting movement of the clutch shoes. |
