<p>PURPOSE:To reliably increase response speed from input to output during transmission of power. CONSTITUTION:A solar gear 4 and a first drum 5 are integrally mounted on an input shaft 1 and an output shaft 2, respectively. A planetary gear 6 is geared with the solar gear 4 and an internal tooth gear 8 with the planetary gear 6. A second drum 10 is arranged in position opposite to the first drum 5, the first and second drums 5 and 10 are intercoupled through a coupling shaft 9, and the planetary gear 6 is supported on the shaft 9. First and second coil springs 13 and 14 are wound around a casing 3 and the first drum 5 and the casing 3 and the second rum 10, respectively. A square key 30 is attached to the internal tooth gear 8 and a notch groove 31 is formed in a dry bearing 15 formed integrally with the casing 3. Through contact between the square key 30 and the notch groove 31, rotation of the internal tooth gear 8 is regulated. The end parts of the first and second coil springs are locked to the square key 30.</p> |
