Abstract: A friction material (1) comprising a flame sprayed metal film (4) in an amount of 10 mg/cm.sup.2 which is formed on at least whole range of outer peripheral side of an annular friction surface (3) provided at center with large diameter hole (2), of which radial length (B) is one-third of radial length (A) from outer periphery of said friction surface (3) to said large diameter hole (2).

Abstract: A clutch facing (1) having an annular friction material (3) and reinforcing plate (4) integrally connected to the friction material (3) characterized by that the reinforcing plate (4) having substantially the same shrinkage as the friction material has, an annular rib (6) concentrically formed on the connecting surface (5) of the reinforcing plate (4), and radial ribs (7) formed on the connecting surface (5) and crossing the annular rib (6).

Abstract: A clutch cover assembly has an annular pressure plate; a forcing device for forcing the pressure plate toward a clutch disc; and a connecting device connecting the pressure so as to be unrotatable but axially movable relative to a clutch cover. The pressure plate is divided into (a) a support member positioned adjacent to the clutch cover and connected to the forcing device and (b) a pressure member positioned adjacent to the clutch disc for pressing the clutch disc. Both of the support and pressure members are unrotatably and axially elastically connected by an elastic device so that an axial clearance may be formed between both members when the clutch is released.
