PURPOSE:To miniaturize, and facilitate the machining of the captioned clutch disk by employing a cam mechanism in which inclined faces are made a cam face and a recessed groove side contact piece is made a cam follower, as a damping means. CONSTITUTION:Recessed grooves 14, 13 each having a parabolic contour in the circumferential direction are provided on a driving side member and a driven side member respectively, and a sliding contact member 16 is fitted between the opposite face 15 and the bottom faces of the recessed grooves 13, 14. The sliding contact member 16 consists of a contact piece 17 which is slidingly brought into contact with and astride both bottom faces of the recessed grooves 13, 14, a contact piece 18 which is slidingly brought into contact with the opposite face 15, a spring 19 interposed between both contact pieces 17, 18, and a rubber cylindrical piece 20 surrounding the spring 19. When variation occurs in transmitting torque between the driving side member and the driven side member causing both members to relatively rotate, the contact piece 17 is intervened between the inclined face (14c or 14b) of the recessed groove 14 of the driving side member on one end portion and the inclined face (13b or 13c) of the recessed groove 13 of the driven side member on the other end portion to be slidingly pushed up on both inclined faces and the variation in torque can be damped down by the friction force at this time. |
