<p>PROBLEM TO BE SOLVED: To provide a clutch mechanism for selectively transmitting rotating movement in the normal direction and the reverse direction. SOLUTION: By the rotation of a gear 135 rotating in the direction of the arrow mark 160, a winding spring 145 installed to a hub 155 is bulked so as to engage with a sleeve 115, and its rotation is transmitted to an output shaft 125 finally. On the other hand, when a current is fed to a coil 105, a floating control link 130 is attracted to a shoulder 165, and by the rotation of a gear 170 in the direction of the arrow mark 175, the engagement of the spring 145 and the sleeve 115 is removed so as to transmit the rotation of the gear 170 to the output shaft 125.</p> |
