Abstract
A multiple disc clutch apparatus, comprises a plurality of externally splined annular friction plates, to one side surface only of each externally splined annular friction plate being fixed a friction material, and each externally splined annular friction plate being formed with engagement teeth at an outer periphery, a plurality of internally splined annular friction plates, to one side surface only of each internally splined annular friction plate being fixed a friction material, and each internally splined annular friction plate being formed with engagement teeth at an inner periphery. The externally splined friction plate and the internally splined friction plate are alternately arranged in a direction in which the frictional materials are not overlapped each other. An annular externally splined separator plate provided with engagement teeth on the outer peripheral surface thereof is interposed between a frictional material bonding surface of the internally splined friction plate and the externally splined friction plate. An internally splined annular separator plate provided with engagement teeth on the inner peripheral surface thereof is interposed between a frictional material bonding surface of the externally splined friction plate and the internally splined friction plate.
