ABSTRACT:
A clutch diaphragm, especially for a motor vehicle clutch, comprises a peripheral portion defining a Belleville ring, and a central portion which is divided into radial fingers by radial slots, each terminating in an aperture in the vicinity of the root zone of the radial fingers. Local dimples are formed in the Belleville ring portion of the diaphragm, each in register with a corresponding one of the apertures so as to reduce the peaking effect of the characteristic curve of the diaphragm.
