Abstract
The friction clutch for a motor vehicle comprises a fly-wheel having a clutch cover on which a diaphragm spring is supported through retaining bolts. The retaining bolts axially displaceably pass through the diaphragm spring and the clutch cover and are secured on the side axially remote from the diaphragm spring on a plate spring which is supported on the clutch cover. The plate spring carries all retaining bolts and concentrically surrounds the rotation axis of the clutch. The plate spring ensures play-free clamping in of the diaphragm spring. The plate spring is preferably independently centered on the clutch cover so that the passage openings of the retaining bolts can be of such large dimensions that no friction occurs.
