Abstract
A clutch release arrangement for a clutch includes a pressure plate arranged in a clutch cover and having a fulcrum portion on its external circumference. A diaphragm spring is supported in the region of its external circumference to the clutch cover. The clutch is released by pressing the pressure plate in the direction of a clutch disk through the connection of the fulcrum portion of the pressure plate to the diaphragm spring. A return spring is arranged between the clutch cover and the diaphragm spring and in contact with the diaphragm spring, and the fulcrum portion is a continuously curved surface formed so that the height of the fulcrum portion is low in proportion to the distance between the fulcrum portion and a contact point.
