Abstract:
1. A reclining device comprising: a plurality of pawls having outer teeth; a ratchet having on an inner peripheral side thereof inner teeth that mesh with the outer teeth; a holder that rotates concentrically with respect to the ratchet and that holds the pawls such that the pawls can move selectively toward and away from the inner teeth of the ratchet; a cam body that moves the pawls toward the ratchet and brings the pawls into mesh with the ratchet to prevent the holder and the ratchet from rotating relative to each other, and that moves the pawls away from the ratchet and brings the pawls out of mesh with the ratchet to allow the holder and the ratchet to rotate relative to each other; and an unlock member that holds at least one of the p awls that has moved away from the ratchet while the holder and the ratchet form a relative rotational angle within a predetermined range and that sets a first angular range where the at least one of the pawls is out of mesh with the ratchet, and a second angular range where the-pawls adjacent to the at least one of the pawls move to mesh with the ratchet such that the first and second angular ranges overlap with each other in a plan view.
