Abstract
A clutch mechanism comprising a cover plate having a base portion joined to a skirt portion, a pressure plate and a diaphragm. The cover plate has a first shoulder which extends toward the base portion, while the pressure plate has, at its outer periphery, a second shoulder extending away from the base portion. The second shoulder is axially closer to the base portion than the first shoulder. A resilient compensating element is fitted between and in engagement with the first and second shoulders, and biases the pressure plate towards the base portion of the cover plate in such a way as to oppose the increase in the force of the diaphragm that may arise in operation.
