Abstract
A clutch driven plate having an annular component which carries the friction facings and which is mounted for limited rotary movement on a hub so that it extends between a pair of radially extending discs which are fixed to the hub. One or both discs have integral bent-over tongues which project into corresponding circumferentially extending slots in the annular component and serve as stops which limit the rotary movement of the annular component relative to the hub. Also at least one of the discs is fixed in relation to the hub by engagement in grooves formed in the hub of serrations formed in its inner peripheral edge or vice versa. The serrations may be formed of a material which is harder than that in which the grooves are formed, the grooves being cut by the serrations during assembly of the disc onto the hub. Alternatively both the serrations and the grooves may be preformed and the serrations may be engaged within the grooves with an interference fit.
