ABSTRACT:
The object of the invention is to provide a reclining device which improves engagement between a lock gear and a gear plate for reliable locking without requiring high dimensional accuracy. Four lock gears comprising a pair of first lock gears40, and a pair of second lock gears50in which a gap between the second lock gear50and guide protrusions12, 13is larger than a gap between the first lock gear40and guide protrusions11, 12are adopted. Due to elastic function of a biasing member body90aof an biasing member90, both the second lock gears50are biased radially and inwardly and toward the guide protrusion13of the base plate10.
