ABSTRACT:
A clutch is provided which comprises a first rotatable member, a second rotatable member provided for rotational movement relative to the first rotatable member, a coil spring wound around the first and second rotatable members, and a one-way brake. Rotation of the second rotatable member in at least one direction causes the coil spring to contract so as to fasten together the first and the second rotatable members to rotate synchronously. The one-way brake is adapted for restricting the coil spring from rotating in the winding direction and allowing it to rotate in the release direction so as to allow independent rotation of the first and second rotatable members. Therefore, power can be transmitted to the first rotatable member from the second rotatable member but not in the other direction.
