The invention relates to a torsional-vibration damping hub for a clutch friction plate. The hub comprises two coaxial parts mounted for limited relative angular displacement against the action of circumferential springs disposed between the parts. Axially-acting spring means are also provided for acting on friction means disposed between the parts, and these spring means comprise a clamping disc provided with elastically deformable, radially projecting lugs. These lugs extend from the internal periphery of the clamping disc and are each bent to form a dihedral angle. This arrangement enables an improved distribution of the axial clamping force over known arrangements.
