PURPOSE:To suppress the occurrence of eccentricity and the fall of a power transmission gear arranged between a pair of input discs or output discs the backs of which are positioned facing each other. CONSTITUTION:The backs of a pair of input discs 5 and 9 are arranged facing each other. A loading cam 16 and an intermediate disc 15 with the outer periphery of which a power transmission gear 18 for an input is formed integrally are respectively arranged between a pair of the input discs 5 and 9. The inner peripheral part of the intermediate disc 15 is axially extended and an extension part 15a is rotatably supported directly on an output shaft 1 by means of bearings 90 and 90 axially arranged in two spots. Thus, compared with indirect support of the power transmission gear 18 on the output shaft 1 through a member, such as a tube, eccentricity of the power transmission gear 18 from the output shaft 1 and the fall thereof and the generation of noise and vibration owing to defective engagement of the power transmission gear 18 occasioned by the eccentricity are reduced or prevented from occurring.
