ABSTRACT:
A reclining adjuster has a lower bracket fixed to a seat cushion; an upper bracket fixed to a seatback and connected to the lower bracket so as to be rotatable about a shaft; a lock mechanism capable of having a locked state where rotation of the upper bracket relative to the lower bracket is locked and a released state where the lock is released; and an emergency lock mechanism for preventing relative rotation between the lock mechanism and the upper bracket when it occurs. In the emergency lock mechanism, when a cam projection of an outer toothed ring gear is pressed in the circumferential direction by a cam pin of a disk member by the relative rotation therebetween, the outer toothed ring gear meshes with both inner teeth of the lower bracket and inner teeth of the upper bracket.
