Abstract
A diaphragm clutch, especially of the push-off type, has a metallic, annular, dished cover plate which comprises a junction zone which joins a base, oriented generally transversely, to an annular skirt oriented generally axially. The cover plate is in two parts, namely a base which is secured by welding to the junction zone, the latter being part of the second or outer part of the cover plate and comprising the skirt which is integral with the junction zone. The second part of the cover plate can be a standard cover plate usually employed in a pull-off clutch.
