ABSTRACT:
Disclosed is a clutch disk comprising a clutch hub including a flange formed on an outer periphery thereof, the flange having a plurality of openings, a first side plate including a plurality of openings, a second side plate including a plurality of openings, a plurality of dampers disposed in the openings of the flange of the clutch hub, the first side plate and the second side plate, and including an elastic member tapering from wide to narrow in an axial direction thereof away from one end thereof to a central portion thereof and tapering from narrow to wide in an axial direction thereof away from the central portion thereof to another end thereof, and sheet members disposed on both ends of the elastic member, and a facing connected to one of the first side plate and the second side plate. Since the elastic members deform less in radial directions when the clutch disk operates, it is necessary to enlarge the sheet members in radial directions only by a miniumum required dimension in order to inhibit the elastic members from interfering with the flange of the clutch hub, and the first and second side plates. Thus, the clutch disk can be down-sized in an axial direction. Further, stresses caused by a rotational moment, can be reduced and inhibited from concentrating on the both ends of the elastic members. Thus, the durability of the dampers can be improved.
