In the present invention, a one-way clutch has an input gear, a planet gear provided in the input gear, an output gear, a stopper wall. When the input gear rotates in the backward direction, the stopper wall is separated from the planet gear. Wherein any one of the planet gear and the input gear has a boss being coaxial with the center of the other of the planet gear and the input gear, and the other of the planet gear and the input gear has a groove in an elongated hole shape which the boss fits in. When the input gear rotates in the forward direction, the boss slides to one end of the groove, and the planet gear is wedged between the stopper wall and the inner teeth. When the input gear rotates in the backward direction, the boss slides to the other end of the groove so that the planet gear separates from the locking member.
