ABSTRACT:
A clutch mechanism for selectively setting up or interrupting the delivery of a drive force in accordance with a direction and an amount of rotation of a shaft is disclosed. The mechanism includes a clutch gear rotated by the rotation of a motor. A slide cam is supported by a clutch shaft in such a manner as to be unrotatable relative to the shaft. Ratchet portions respectively provided on the clutch gear and slide cam are selectively coupled or uncoupled in accordance with the direction of rotation, thereby setting up or interrupting drive transmission. A cam portion is formed integrally with the slide cam and releases the ratchet portions when a pin is brought to a preselected position on a cam surface. A cam lever selectively moves the pin toward or away from the cam surface in accordance with the direction of rotation of the clutch gear. The drive source can be shared by a driveline for rotating a shaft to a preselected angular position and other drivelines.
