ABSTRACT:
In a friction clutch including a diaphragm spring for urging a pressure plate into pressing a clutch disk against a flywheel, a support ring member for supporting the diaphragm spring from the back with respect to the clutch cover is normally urged toward the pressure plate, but restrained by a resilient spacer member which is provided on the pressure plate. The resilient spacer member normally restrains the support ring member against the urging force but, once the clutch disk is worn and the pressure plate is thereby caused to move closer to the flywheel, allows the support ring member to move toward the pressure plate by a distance corresponding to the wear in the clutch disk. The back support point of the diaphragm spring is thus moved toward the flywheel according to the amount of wear which develops in the facing members of the clutch disk, and this adjusting action can be achieved with a simple arrangement and in an stable and immediate manner.
