ABSTRACT:
A friction clutch wherein the leaf springs which confine the pressure plate to axial movement relative to the housing are secured to the pressure plate by fastening devices having solid or tubular connecting elements a first portion of each of which is anchored in a discrete blind bore of the pressure plate and each of which extends outwardly through and beyond an opening in the respective leaf spring. Those portions of the connecting elements which extend outwardly beyond the openings of the respective leaf springs are deformed to constitute rivet heads which overlie the leaf springs and hold them against movement away from the respective surface of the pressure plate. Such mode of fastening the leaf springs to the pressure plate allows for a reduction of the radial dimensions and weight and enhances the safety of the clutch, especially as concerns the bursting strength of the pressure plate.
