Abstract
A friction clutch disc comprises an annular support plate and annular friction facings on the respective sides of the support plate. Bores in the friction facings are generally in axial alignment with openings in said support plate, and rivets secure the respective friction facings to the support plate through pairs of aligned bores and openings. Each rivet comprises a shank, a first head at one end of the shank bearing against a transverse, and preferably flared, shoulder adjacent the axially inner end of the associated bore and a second head at the other end of the shank bearing against the support plate around the margin defining the associated opening therein. An annular protrusion coaxial with each of the bores in at least one of the friction facings is axially in alignment with and inwardly of the associated shoulder and is at least partly received in the associated opening in the support plate.
