A reclining apparatus (20) is provided with a fixed plate (21) having guide portions (41, 42), a shaft (30), a rotary plate (22) having an internal gear (66), slide gears (70, 71), a cam member (72) and the like. The cam member (72) has a pair of hook portions (100) engaging with a receiving portion (87) in the slide gears (70, 71). The hook portion (100) and the receiving portion (87) are formed in such a shape as to move the slide gears (70, 71) in a direction of canceling a rotational moment applied to the slide gears (70, 71) due to a backward load applied to the seat back when the cam member (72) rotates in a lock canceling direction. A supporting portion (120) preventing the slide gears (70, 71) from moving in a direction of the rotational moment is provided in an opposing portion between the cam member (72) and the slide gears (70, 71). <IMAGE> |
