摘要：
A diaphragm spring for a friction clutch includes a ring-like body area and a plurality of spring tongues arranged at the inner edge in a row in a circumferential direction and extending radially inward from the body area. Openings are formed between adjacent spring tongues, each opening having a radially outer base area, at least one of the openings being limited in the circumferential direction by a wall area having a curvature which increases as the wall proceeds from the base area.
