Abstract:
1. A clutch mechanism, comprising: a rotatable input element to receive torque; an output element to output the torque; a transmission element rotatable in a first direction and a second direction opposite to the first direction, including integrally a plurality of projections, a rotation restriction device including a first restriction surface and a second restriction surface to contact the first planar surface and the second planar surface of the projections of the transmission element, respectively, to lock rotation of the transmission element; and a moving device including an actuator to move the rotation restriction device to contact and separate from the projections of the transmission element, wherein the torque received by the input element is transmitted to downstream rotary devices in the direction of transmission of torque via the output element while the rotation restriction device engages the projections of the transmission element, wherein the torque received by the input element is not transmitted to the downstream rotary devices via the output element while the rotation restriction device is disengaged from the projections of the transmission element, wherein the first restriction surface contacts the first planar surface while the transmission element rotates in the first direction, and the second restriction surface contacts the second planar surface while the transmission element rotates in the second direction.
