Claims

[Scope of utility model registration request]

A clutch disk is provided between the flywheel and a pressure plate in the clutch cover, and the pressure plate is moved toward the flywheel by the biasing force of a diaphragm spring provided between the clutch cover and the pressure plate. In a friction clutch that transmits driving force by pressing the clutch disk and sandwiching the clutch disk, a part of the clutch cover is connected to the diaphragm spring, and when the ambient temperature reaches a predetermined value, the biasing force of the diaphragm spring is reduced. A friction clutch characterized in that the clutch cover is provided with a bimetal that is displaced to increase the friction.
