Abstract

The clutch disc for a motor vehicle friction disc clutch comprises a hub part from which a hub flange provided with radially outwardly protruding teeth protrudes radially. A disc part provided with clutch friction linings which comprises an annular disc provided with radially inwardly protruding teeth is mounted rotatably on the hub part. The teeth of the hub flange and the annular disc engage in one another with play in the circumferential direction. The annular disc and the hub flange comprise at least one pair of mutually radially opposite apertures each having two stop faces directed towards one another in the circumferential direction. The stop faces, preferably of the annular disc extend over substantially the entire radial height of a spring arranged in the aperture of this part. The spring is supported on the stop faces of the other part through a retaining stirrup piece which is U-shaped seen in the circumferential direction. The retaining stirrup piece has legs on both axial sides which hold the spring in the circumferential direction between them. The spring couples the annular disc rotationally elastically with the hub disc in idling operation.
