Abstract
A clutch assembly comprising an annular cover, a pressure plate rotationally connected to said cover, a resilient annular diaphragm, and an annular element pivotably connecting said diaphragm to said cover. Tha annular element is provided with a radially extending annular portion which resiliently engages the diaphragm and with axially extending circumferentially spaced tabs which project through facing apertures in the diaphragm and in the cover. Each tab carries a resilient lug capable to be housed in an opening in the tab during installation of the element, the free end of said lug normally engaging the cover after predetermined axial stressing of the annular portion of the annular member after installation of the latter.
