ABSTRACT:
A clutch, which is applicable to the applications where an electromagnetic clutch is conventionally used, is provided in order to realize the reduction of the clutch in size, weight and cost and the power saving of the clutch. A clutch according to the present invention includes: an input gear to which a rotational torque is input; a clutch member attached to an inner circumferential face of the input gear; a tapered roller acting as an engaging element; a retainer for holding the tapered roller; a cap member; a waved spring; an output shaft serving as a driven member; a housing for sheathing the input gear; a working member equipped with an operating lever; and a return spring serving as an elastic return member, for elastically supporting the working member. With a simple operation of pivoting the operating lever of the working member, the clutch can be easily switched between a state where the tapered roller is engaged in a wedgewise manner so as to drive and rotate the output shaft and a state where the wedge engagement of the tapered roller is cancelled to freely rotate the output shaft.
