Abstract
In order to avoid undesired spring force variations of a diaphragm spring (13) of a friction clutch by reason of centrifugal forces it is proposed to provide the spring tongues (17) between their tongue ends (25) and a basic body (15) of the diaphragm spring (13) with outwardly domed portions (31) by which the center of gravity (33) in the position of the diaphragm spring (13) endangered by centrifugal force is shifted into the plane of radial supporting of the diaphragm spring (13).
