PURPOSE:To improve power transmission performance, by a method wherein a cylindrical surface, being eccentric to an output shaft, is formed on the outer periphery of an output member, the inner periphery of a rubber ring is slidably engaged with the cylindrical surface, and the outer periphery of the rubber ring is fastened to an input member. CONSTITUTION:A hub 1, being an output member, is provided at its outer periphery with a flange 2, and the center A-A of its outer peripheral surface 3 is positioned eccentrically to an output shaft center O-O. A slide ring 8 is engaged with the outer peripheral surface 3, and the inner peripheral surface of a rubber ring 9 is engaged with the outer peripheral surface of a ring 8 to be secured thereto. The ring 8 is positioned concentrically centering around the axis A-A, meanwhile, the outer peripheral surface 11 of the rubber ring 9 is concentric to the axis O-O. A pair of side plates 12 and 13, being an input member, are provided at the inner peripheral surface thereof with cylindrical flanges 15 and 16 rotatably engaged with the outer peripheral surface of the hub 1, and the outer peripheral surface of the rubber ring 9 is secured to the inner peripheral surface of the bent cylindrical part 17 of a plate 12 on one side. |
