Abstract
In a clutch unit of the diaphragm spring type a support ring is positioned between a clutch cover and a diaphragm spring. The diaphragm spring is fastened to the clutch cover by noses of the diaphragm spring which encompass the support ring on the one hand and by projections of the clutch cover which also encompass the support ring on the other hand. The noses are accommodated by apertures of the clutch cover and the projections are accommodated by openings of the diaphragm spring. The support ring is an open support ring so that it can be inserted in radially outward direction between the diaphragm spring and the projections on the one hand and the clutch cover and the noses on the other hand.
