The invention relates to a friction clutch which comprises a housing and a pressure plate which is linked therewith in a rotationally fixed manner but which can be displaced in an axially limited manner. A pivoted lever system is arranged between the housing and the pressure plate and is used to actuate the pressure plate for engaging and disengaging the friction clutch. The lever system comprises a plurality of lever elements positioned in a circle around the rotational axis of the friction clutch. The invention is characterized in that an annular component (23) is functionally linked with the lever system (8) in such a manner that it is radially flared and reduced when the lever system is pivoted. The annular component comprises two distal areas one of which is stationary relative to the lever system in at least one peripheral direction and the other one is subject to a substantially linear displacement during expansion and reduction, said linear displacement triggering an actuation of an adjustment device which twists the lever system.
