Abstract:
1. A reclining apparatus comprising: a bottomed cylindrical first member formed with inner teeth on an inner cylindrical surface along the circumferential direction; a second member stacked on a side of an opened surface of the first member and provided so as to be capable of rotating relative to the first member in the circumferential direction; a pawl provided on the second member so as to be capable of moving and formed with outer teeth capable of engaging the inner teeth; a rotation cam provided so as to be capable of rotating about an axis of the relative rotation, formed with a non-circular through hole at a center of rotation, and configured to move the pawl to a locked position where the outer teeth of the pawl engage the inner teeth of the first member by rotation in one direction; an operating shaft fitted to the non-circular through hole of the rotation cam and configured to rotate integrally with the rotation cam; and a spiral spring engaging the operating shaft at an inner end portion thereof, engaging the second member at an outer end portion thereof, and configured to urge the rotation cam so as to position the pawl in the locked position, wherein the operating shaft is formed with a flange portion on an outer peripheral surface thereof so as to protrude in the radial direction of the operating shaft so as to abut against a bottom portion of the first member and restrict the operating shaft from inclining in any direction with respect to the bottom portion of the first member, and the rotation cam faces a surface of the flange portion, the surface being opposite to a surface of the flange portion abutting against the bottom portion of the first member.
