PROBLEM TO BE SOLVED: To stabilize spring characteristics, that is, clutch pressing force and clutch releasing force (release operating force) by stabilizing a radial position of a pressing member such as a diaphragm spring, in a device performing clutch operation by using a lever mechanism. SOLUTION: This device comprises a clutch housing 1, an output-side rotor 2, a clutch portion 3, a pressure plate 4, and a diaphragm spring 5. The clutch housing 1 is connected with an input-side member, and the output-side rotor 2 is connected with an output-side member. The clutch portion 3 has a plurality of clutch plates, and the pressure plate 4 presses the clutch plates to each other. The diaphragm spring 5 presses the pressure plate 4. A circular projecting portion 4b axially projecting, is formed on an outer peripheral portion of the pressure plate 4, an outer peripheral face of the diaphragm spring 5 is supported by an inner peripheral face of the circular projecting portion 4b, and thus the diaphragm spring 5 is radially positioned.
