Clutch cover assembly

Abstract

A clutch cover assembly comprises an annular clutch cover, a pressure plate connected to the clutch cover, a diaphragm spring elastically disposed between the pressure plate and the clutch cover and supported circumferentially and radially to the clutch cover by a supporting member inserted into a hole formed therein and supported axially to the clutch cover through an annular member located between the inner wall of the clutch cover and the one end of the supporting member. The diaphragm spring is used for biasing the external portion of the pressure plate in the opposite direction to the clutch cover. A spring member includes an outer periphery which is located at an inward of the annular member and which is attached to the clutch cover and, an inner periphery which is located at a further inward of the outer periphery and which is attached to the diaphragm spring. The spring member is used for establishing a biasing force in the opposite direction to said clutch cover by an annular portion defined between the outer periphery and the inner periphery so as to prevent the load of the diaphragm spring from increasing as a facing of a clutch disk wears.
