The second sleeve (12) is axially movably. The first lever plate (16) is an annular member, which is fixed to an outer periphery of the second sleeve (12) and has a spherical convex surface (16a) opposed to a transmission. The second lever plate (17) is an annular member, which has a spherical concave surface (17a) in slidable contact with the spherical convex surface (16a) and is in contact with an inner peripheral end of the diaphragm spring (9).
