For the clutch disc of a motor vehicle friction clutch, it is proposed that one of the side discs (13) of a rotational oscillation damper of the clutch disc be supported via a radially elastic bearing ring (21) on a cylindrical bearing surface (25) of a hub (3) of the clutch disc. The bearing ring (21) has a closed ring part (65) which is radially and axially fixed in a central opening (23) of the side disc (13) and, on its inner circumference, has an essentially conical, preferably radially slotted, radially elastic connecting region (73). The connecting region (73) is provided on its inner circumference, either directly or via an integrally formed sleeve region (75), with a cylindrical opposing bearing surface (77) which rests essentially without pretensioning on the bearing surface (25) of the hub (3). Spacer blocks (79) limit the radial spring movement and are used for the rotationally fixed guidance of the bearing ring (21) on the side disc (33).
