PROBLEM TO BE SOLVED: To improve fuel economy in consideration of a leak amount of oil.SOLUTION: An oil supply device 200 includes an oil pump 81, an oil pressure sensor 50a for detecting an oil pressure of an oil supply passage 5 through which oil delivered from the oil pump 81 flows, and a controller 60 for controlling the oil pressure of the oil supply passage 5 by adjusting capacity of the oil pump 81 based on a detection result of the oil pressure sensor 50a. The controller 60 controls the oil pressure of the oil supply passage 5 in accordance with engine speed, and in an operation region where the engine speed is equal to or lower than a prescribed value, the controller 60 controls so that the higher an oil temperature is, the lower the oil pressure of the oil supply passage 5 in accordance with the engine speed is.SELECTED DRAWING: Figure 14 |
