<p>PROBLEM TO BE SOLVED: To improve engaging responsiveness by excellently swishing off oil film from the friction surface of a frictional plate while the lubrication effect of a wet multiple disc clutch is maintained. SOLUTION: Clutch plates 45 supported with a clutch guide 42 and clutch discs 46 supported in a clutch center 44 are mutually put over, and a disc spring 74 arranged at one end thereof is engaged with them by being pushed and pressed by a clutch piston 48. The clutch guide 42 is equipped with the clutch plate 45 and an oil hole 79 from which lubricant oil by which the clutch disc 46 is cooled is discharged, and also equipped with an oil hole 80 from which lubricant oil leaked from a clearanceαbetween the disc spring 74 and the clutch piston 48 is discharged. When the oil film between the clutch plate 45 and the clutch disc 46 is swished off at an initial stage that a clutch is engaged, the oil film can be rapidly swished off by spilling the lubricant oil from the clearanceα.</p> |
