1. A one-way coupling, comprising:
an input shaft to which a drive force is inputted; and
an output shaft that outputs the drive force,
wherein the one-way coupling is configured to transmit the drive force from the input shaft to the output shaft, and inhibit the drive force inputted to the output shaft from being transmitted to the input shaft,
the one-way coupling further comprising:
a transmitter comprising:
an input-side protrusion rotating integrally with the input shaft, and
an output-side protrusion rotating integrally with the output shaft, the input-side protrusion and the output-side protrusion being engaged with each other when the drive force is inputted to the input shaft, thereby to transmit the drive force from the input shaft to the output shaft;
an immovable ring held in a non-rotatable state;
a pressure-contact cam rotating integrally with the output shaft;
a first wedge member displaceable between a locked position and a unlocked position, the first wedge member being brought into pressure contact with a circumferential surface of the immovable ring at the locked position, the pressure contact being released at the unlocked position, the first wedge member receiving a pressing force from the pressure-contact cam when the drive force is inputted to the input shaft, thereby to be displaced to the locked position; and
a first holder provided to the first wedge member, and holding an arrangement of the first wedge member when the drive force is inputted to the output shaft.
