ABSTRACT:
A reclining device for a seat, comprising a stationary base plate and rotatable plate, both being fitted together, with the rotatable plate free to rotate relative to the base plate. An annular toothed portion and an unlock area are respectively formed in either of those two plates, and a lock gear is interposed between the plates in a vertically slidable manner such that, with the rotation of the rotatable plate, the lock gear is disengaged from the toothed portion and rides on the unlock area, or vice versa, to thereby place the reclining device in a locked or unlocked state, by simply operating a lever to effect such engagement/disengagement of the lock gear to the toothed portion.
