Abstract

A pressure plate assembly for a friction clutch includes a housing arrangement and a pressure plate arrangement, which is held by at least one leaf spring arrangement with freedom of axial movement relative to the housing arrangement. The at least one leaf spring arrangement is fixed by a first attachment area to a first fastening area of the pressure plate arrangement and by a second attachment area to a second fastening area of the housing arrangement. The end area of the first fastening area and/or the second fastening area curves away from the minimum of one leaf spring arrangement, this end area being located in the area along which the at least one leaf spring arrangement extends.
