Abstract
A seat reclining apparatus includes a base plate, a ratchet plate, guide grooves formed on the base plate including an internal gear, lock members installed in the guide grooves and each having an outer toothed portion, and an operating member for moving the lock members between engaged and disengaged positions in which an outer toothed portion is engaged and disengaged with the internal gear, respectively. One of the lock members constitutes a small-clearance lock member which is smaller in play in a circumferential direction relative to a guide groove than the remaining lock members when in the engaged position. The small-clearance lock member is provided at the smallest distance between an engagement central position, at which the outer toothed portion and the internal gear are centered about, and an upper end of the seatback side frame.
