- a holder attached to a back surface of the backrest portion,
- a reel housed in the holder and supported by the holder so as to be rotatable in both forward and reverse directions,
- a cord connecting the body and the backrest portion and configured to change the tilt angle of the backrest portion as the reel winds up and lets out the cord,
- a lock member housed in the holder and configured not to allow rotation of the reel, wherein the lock member includes an engaging pawl that is displaceable between a first position where the lock member is engaged with a portion that rotates with the reel so as not to allow the rotation of the reel and a second position where the lock member is disengaged from the portion that rotates with the reel so as to allow the rotation of the reel,
