A clutch includes plural tabs formed on an internal circumference of a clutch cover and bent toward a pressure plate through an opening provided on one end of a slit of a diaphragm spring. The diaphragm spring has plural pivot rings arranged on either side of the diaphragm spring and supported by the tab. The tabs are divided into at least two types. A long wide tab and a short wide tab, shorter than the long wide tab, permit the connecting force and the bending load of the plural pivot rings and the diaphragm spring to be reduced.
