Abstract
The seat reclining apparatus includes first and second pawls supported by a base member to be movable in radial directions and to be engageable with an internal gear of a ratchet. In the unlocked range, a first pawl-restriction portion of the ratchet and a first limit portion of the first pawl, which are positioned on the radially outer side, radially face, and each pawl is prevented from engaging with the internal gear. In a specific range of the unlocked range, a second pawl-restriction portion of the ratchet and a second limit portion of the second pawl, which are positioned on the radially inner side, radially face. The second pawl-restriction portion or/and the second limit portion includes a pressing portion which moves the second pawl to a disengaged position when the second-pawl restriction portion and the second limit portion mutually contact in the rotational direction of the ratchet.
