Abstract: An autotensioner for a belt has a pulley support shaft secured to a base and an eccentric ring rotatably supported by the pulley support shaft with the center of its outer peripheral surface offset from the center of the pulley support shaft. A pulley is rotatably supported around the eccentric shaft through a rolling bearing. A spring for biasing the eccentric ring is provided to press the pulley against the belt. A damper for imparting resistance to rotation to the eccentric ring is provided to restrain the pivoting motion of the pulley. The resistance to rotation is imparted to the eccentric ring by the damper at the side of the rolling bearing opposite to the base.

Abstract: PROBLEM TO BE SOLVED: To provide a wheel driving device in which, when an inner gear is vibrated by torque transmission to the inner gear, the vibration can be prevented from being transferred to a reduction gear casing.SOLUTION: A reduction gear 20 which reduces a rotating speed of an electric motor 10 and transfers the rotation to a wheel supporting hub ring 51 is made into cycloid reduction gear. Whirling of an inner gear 26 to which an outer gear 24 of the cycloid reduction gear is meshed, is stopped to a reduction gear casing 21 by whirl stop means 40, and an elastic support function for elastically supporting the inner gear 26 is given to the whirl stop means 40. Therefore, when vibrations are loaded to the inner gear 26 in transmitting rotation torque from the outer gear 24 to the inner gear 26, the vibrations are absorbed by elastic deformation of the whirl stop means 40 and prevented from being transferred to the reduction gear casing 21. An output shaft 28 of the cycloid reduction gear is spline-fitted to a cylinder part 36 of a pin holder 33.
