Abstract
The dial recliner includes a holder and a sector gear and also comprises a brake spring, a cam, a pair of clutch shoes and a spring which are accommodated and supported between the holder and the sector gear. The dial recliner also comprises a housing to maintain a combined state between the holder and the sector gear. The holder has inner teeth of a ring shape at its outer circular part and a boss at its center part to support a shaft. The sector gear has outer teeth to intermesh with the inner teeth of the holder. When intermeshed, the boss of the holder and a shaft hole of the sector gear become eccentric between their centers. The clutch shoe is supported by the brake spring which is elastically held around the boss of the holder so that a circular drifting movement of the clutch shoe can be prevented.
