ABSTRACT:
A manufacturing method of a clutch cover assembly comprising a first process in which an annular clutch cover body of a clutch cover is formed, a plurality of projections extending substantially radially inwardly from the inner periphery of the clutch cover body are formed and ends of said projections are bent so that the projections may extend in an axially inside direction of the clutch cover and toward a center of the clutch cover; a second process in which projection bodies between the clutch cover body and said projection ends are bent so that the projection bodies may extend in the axially inside direction of the clutch cover and toward the center of the clutch cover; and a third process in which a diaphragm spring and a pair of wire rings disposed at both sides of said spring for forming fulcrums for the spring are assembled to the projections, and then, the projection bodies are bent in a radially outward direction of the clutch cover and the projections ends are bent toward the inner peripheral portion of the clutch cover.
