ABSTRACT:
The pressure plate for a motor vehicle friction clutch comprises a clutch cover, a non-rotatable but axially displaceable presser plate and a diaphragm spring which is supported in the region of its external circumference on the presser plate and on a smaller diameter on the clutch cover. Securing elements retained on the clutch cover pass through openings of the diaphragm spring and hold the diaphragm spring between the two wire rings, of which the wire ring placed on the side of the presser plate is axially undulated. The regions of the wire ring which form undulation crests in relation to the diaphragm spring extend below the support faces of the securing elements. A projection is formed by bending or as additional part on the wire ring and fixes the wire ring non-rotatably.
