ABSTRACT:
In a twin-clutch, an intermediate plate is configured to be located reliably at a position intermediate a pressure plate and a flywheel. The annular intermediate plate 31 is disposed between first and second frictional coupling portions. A clutch cover assembly includes a clutch cover 4 fixed to the flywheel 1, a pressure plate 30 disposed near the second frictional coupling portion, and a diaphragm spring carried by the clutch cover 4 for biasing the pressure plate 30 toward the flywheel 1. Strap plates 35 couple the flywheel 1 to the intermediate plate 31, and bias the intermediate plate 31 away from the flywheel 1 when the clutch is engaged. Coil spring 42 is arranged in a compressed state between the pressure plate 30 and the intermediate plate 31, and has the substantially same spring constant as the strap plates 35.
