ABSTRACT:
An electrically powered drive apparatus comprises a first clutch plate secured to an output shaft and a second clutch plate mounted to a gear which is rotatably and slidably provided on the output shaft. The second clutch plate comprises a resilient transmission member and a magnetically-attracted contact member. The resilient transmission member is secured at a first portion to the gear and is adapted to resiliently deflect. The contact member is secured to a second portion of the resilient transmission member. The resilient transmission member has teeth into which pins extend in meshing engagement. When a clutch coil is energized, the contact member is attracted by the first clutch plate to thereby cause the pins to engage the teeth, thereby transmitting rotational force from the drive source to the gear. When the clutch coil is de-energized, the contact member is released to return to its home position with the aid of the resiliency of the resilient transmission member.
