<p>PURPOSE:To form a clutch so as to continually obtain a sufficient cooling effect, by forming plural grooves, which enable fluid to flow out from the inside to the outside in the radial direction, in the internal peripheral surface of a pressure plate and its side surface, in case of the oil hydraulic pressure forced attaching wet type clutch in a vehicle. CONSTITUTION:When an oil hydraulic pressure forced attaching type clutch 8 is disengaged, oil, injected in the direction of an arrow head B in the drawing, is sprayed to a clutch disc 14 cooling and lubricating it while pressing a pressure plate 14 to the clutch disc 14, and the clutch 8, even when it is placed in a condition that no oil can be allowed to flow out from a part of the clutch disc 14, allows the oil to flow to the outside in the radial direction of the pressure plate 13 passing through grooves 13c and 13d. Further the clutch 8, allowing the oil to flow passing through outflow holes 15c, 15d formed in a clutch cover 15, enables the pressure plate 13, clutch disc 14 and the clutch cover 15 to be cooled also from their outsides.</p> |
