Abstract
A speed reduction device including an overrunning clutch has a drive shaft having an eccentric ring and an inner gear plate disposed to be rotatable relative to the eccentric ring. The gear plate has a plurality of teeth and engagement holes. The device further has fixing pins fixed to the housing in engagement with the engagement holes of the inner gear plate to restrict rotation of the inner gear plate to thereby allow swinging of the gear plate, an outer ring disposed around the inner gear plate and connected to a driven shaft and a torque transmitting member which engages the teeth of the inner gear plate to transmit torque from the inner gear plate to the outer ring. The torque transmitting member is arranged to disengage the teeth of the inner gear plate by centrifugal force when the outer ring rotates at a speed higher than a threshold value.
