PURPOSE:To make the transmitting direction both clockwise and counter-clockwise by using tension of a disc spring and transmitting power by plate-friction torque. CONSTITUTION:Driving force of a motor 1 is rotated in the direction of an arrow 10 by a small gear 3. The driving force of the small gear 3 is transmitted to a large gear 6 and the driving force is transmitted to a shaft 7 fixed by a set screw 8. The small gear 3 is pressed to a spacer 2 by tension of a disc spring 4, and the disc spring 4 is fixed by a nut 5. Accordingly, the spring force of the disc spring 4 can be freely changed by adjusting the nut 5, so that the transmitting direction can be made clockwise and counter-clockwise.
