The clutch disc for a motor vehicle friction disc clutch comprises a hub provided with an external toothing, and two hub discs of which a first hub disc carries on its internal circumference an internal toothing meshing with play in rotation in the external toothing and the other hub disc is connected non-rotatably and without play in rotation with the hub. Axially on both sides of the first hub disc, side discs are connected with clutch friction linings to form a unit mounted rotatably on the hub. Radially within a zone defined by damping springs of the under-load vibration damper, there are provided, axially between the side discs, damping spring of an idling vibration damper which couple the hub disc through the damping springs with the second hub disc.
