<p>PROBLEM TO BE SOLVED: To discharge oil smoothly from a centrifugal pressure cancel plate without causing its deformation or a deterioration in its fatigue characteristic with its centrifugal pressure generating position kept generally unchanged as from existing systems. SOLUTION: The clearance between discharge openings 211 made in a centrifugal pressure cancel pate 2 and a fixing part 3 is widened, not by a radially outward enlargement of the radially outward end nearer to a clutch clamping piston of the discharge openings 211, that is, not by a radially outward shift of the centrifugal pressure generating position. This method smoothes the oil outflow to stabilize the operation of the clutch clamping piston. The periphery of those discharge openings 211 of the centrifugal pressure cancel plate 2 is protruded out opposite to a surface contacted to the fixing part 3.</p> |
