Abstract
A reclining device including a recess formed as a low-rigidity portion in a lateral portion of each of slide pawls which faces a lateral wall surface of a guide groove of a stationary disc (the lateral wall surface of a bearing wall portion). The stationary disc holds the slide pawls. If an enormous circumferential turning force is applied to the slide pawls from a ratchet, the recess functions as a point upon which a pawl body of each of the slide pawls is deflected in the direction in which the turning force is applied. As a result, the pawl body quickly sinks into the lateral wall surface of the bearing wall portion. Thus, the slide pawls are prevented from moving away from the ratchet.
