ABSTRACT:
A reclining device capable of eliminating mechanical play in a front-rear direction of a seat back is provided. Particularly, a reclining device reliably capable of locking and releasing is provided at an inexpensive cost. Movable guides are slidably disposed respectively between lock gears and a fixed guide. Each of the movable guides is formed in a shape that the width thereof gradually decreases from the outer end toward the inner end. In the sliding faces of the respective movable guides, a sliding face on the lock gear side is arranged to be parallel to a movement direction of the lock gear and the sliding face at the fixed guide side is inclined with respect to the sliding face at the side of the lock gear. Each of the movable guides engages with a spring and the spring imparts a force to the movable guides in an inner direction of a base plate.
