<p>PURPOSE:To improve clutch release performance by forming an oil passage to supply pressurized oil to push a piston from the outer periphery of a clutch disc toward the space inside a clutch cover, and forming a gap on the contact surface of the clutch cover and the clutch disc to allow infiltration of pressurized oil. CONSTITUTION:A control valve 14 has a port 16 to supply pressurized oil PC1 to a cylinder 10 behind a piston 11 through an oil passage 15, and a port 19 communicated with an oil passage 18 which supplies pressurized oil PC2 from the outer periphery of a clutch disc to a space 17 inside a clutch cover 6. Furthermore, the outer peripheral edge of the clutch disc 3 is tilted toward the piston 11 to form a gap 21 at a part of the contact surface of the clutch cover 6 and the clutch disc 3. This smoothens lubrication to improve durability, and clutch release performance can be improved with an effect of the gap 21.</p> |
