Abstract
A clutch disc consists of a generally annular drive body connectable to an engine side and rotatably movably connected to a generally annular driven body connected to a vehicle drive line. The drive body is formed with a plurality of radially inwardly extending drive side arms. The driven body is formed with a plurality of radially outwardly extending driven side arms. A fluid chamber to be filled with a hydraulic fluid is formed between each drive side arm and each driven side arm. An orifice is formed between the inner periphery of the drive body and the radially outer-most portion of each driven side arm to provide a flow resistance to the fluid flowing between the adjacent fluid chambers, thereby effectively damping torque fluctuation transmitted from the engine side.
