<p>PROBLEM TO BE SOLVED: To provide a clutch which not only materializes space saving and cost reduction but also can be changed easily to a power reset type and a self reset type. SOLUTION: In condition that the electromagnet of a clutch actuator is not supplied with a current, this clutch actuator does not operate, and a clutch wheel gear 7 is energized to the side of a clutch pinion gear 8 by the spring energizing force of a gear reset spring 19, and one ratchet gear 11 engages with the other ratchet into clutch on condition, and the clutch wheel gear 7 is coupled with the clutch pinion gear 8. Moreover, when the electromagnet of the clutch actuator is supplied with a current, this clutch actuator operates, and shifts the clutch wheel gear 7, resisting the gear reset spring 19, into clutch off condition, which releases the coupling between the clutch wheel gear 7 and the clutch pinion gear 8.</p> |
