<p>PROBLEM TO BE SOLVED: To supply sufficient lubricating oil when a clutch is engaged, decrease the oil when the clutch is disengaged. SOLUTION: A pressing force transmission plate 60 transmitting pressing force of a clutch piston 52 to a clutch plate 56 and a clutch disc 57 is arranged in a clutch drum 51. The pressing force transmission plate is locked to an internal periphery of the clutch drum in an external peripheral end part, also pressed to the clutch piston in an internal peripheral part, to press in an axial direction the clutch plate and the clutch disc in an intermediate part. In a clutch released condition, a guide part 66 connected to an internal peripheral side surface of the pressing force transmission plate allows lubricating oil to flow out to the outside in the sideward of the clutch plate and the clutch disc, in a clutch engaged condition, an internal peripheral part of the pressing force transmission plate is pressed out, the guide part makes the lubricating oil flow in between the clutch plate and the clutch disc.</p> |
