More Information
Summary:A lubrication device constructed using the fact that a first clutch and a second clutch are not engaged at the same time. In the lubrication device, lubrication oil is appropriately distributed according to the state of engagement of the clutches without increasing the total delivery quantity of the oil. A piston (44) for operating the first clutch is provided between a first drum (31) in which the first clutch (C-3) is placed and a second drum (32) in which the second clutch (C-4) is placed. An oil container (87) for containing lubrication oil lubricated the second clutch is provided in the inner circumferential surface of the piston. Dams with different inner diameters are provided at the front and rear in the axial direction of the oil container, and when the quantity of oil supplied to the oil container is increased when the second clutch is not engaged, the lubrication oil is allowed to overflow from the dam (87a) with the smaller diameter and delivered to the first clutch.
