PURPOSE:To perform precise controlling by providing a means for supplying oil from outside to a torque transmission chamber through an oil sending tube, and a breezer for moving gas between the torque transmission chamber and atmosphere when pressure in the torque transmission chamber is out of a specified range, and adjusting an oil amount with high accuracy according to operation conditions. CONSTITUTION:A pump 17 is driven through a signal from a control device 21 based on detected data of a cooling water temperature sensor 24, an engine speed sensor 23 and a fan rotational speed sensor 22. Oil in an oil tank 18 is fed into a case through an oil sending tube 16. When pressure in a torque transmission chamber 7 exceeds a specified upper limit value, gas in the torque transmission chamber 7 is discharged outside a case 4 through a breezer 30, and oil is fed smoothly. The oil in the case 4 is fed back into the oil tank 18 through the oil sending tube 16. When the pressure in the torque transmission chamber 7 is decreased to be lower than a specified lower limit value, external air is flowed into the torque transmission chamber 7 through the breezer 30. The oil is fed out smoothly because the pressure in the torque transmission chamber 7 is not negative pressure. |
