PURPOSE:To heighten the efficiency of motive power transmission, by providing a base gear and a flexible gear having a flexible disk portion, in a casing, by using a push roller to push these gears in the axial direction thereof, and by providing a means for displacing the push roller against the urging force of a spring. CONSTITUTION:A base gear 2 and a flexible gear 6 having a flexible disk portion 6a are provided in a casing 1. A push roller 7 is pushed in the axial direction thereof by a spring urging means 9. A means for displacing the push roller 7 against the spring-urging force of the means 9 is composed of an inclined plate 11, balls 12 and a clutch lever 13. As a result, the efficiency of motive power transmission is heightened. When motive power being transmitted is to be cut off, the clutch lever 13 is operated so that a clutch function is fulfilled. |
