Abstract:
A reclining device, comprising:a plurality of pawls, each of which has first teeth formed in a first end portion thereof, first and second leg portions extending in a direction opposite to the first teeth and formed in a second end portion on the other side of the first end portion where the first teeth are formed and a low-rigidity portion formed in each of the first and second leg portions and demonstrating a lower rigidity than the other portions of the first and second leg portions, wherein the low-rigidity portion is formed at a root of each of the leg portions of each of the pawls; a ratchet which has second teeth that mesh with the first teeth and which can turn within a range where the second teeth are formed so that the first and second teeth can mesh with each other locally and variably; a holder which has a guide groove that abuts on and holds a lateral face of each of the pawls so that the pawls slidably move toward and away from the second teeth of the ratchet; and a cam body which bears on at least one of the first and second leg portions of each of the pawls and presses the first teeth of the pawl toward the ratchet so that the first teeth of the pawl are brought into mesh with the second teeth of the ratchet in order to prevent the holder and the ratchet from rotating relative to each other and which brings the first teeth of the pawl out of mesh with the second teeth of the ratchet so that the holder and the ratchet are allowed to rotate relative to each other.
