PROBLEM TO BE SOLVED: To provide a hydraulic control device of a driving device for a vehicle capable of appropriately and stably supplying an oil regardless of a running state even in supply of a small flow rate, in supplying the oil to an object portion to be lubricated or cooled while switching the flow rate of the oil.SOLUTION: A hydraulic control device of a driving device for a vehicle includes a first switch valve 48 to which a high lubrication hydraulic pressure Phi and a low lubrication hydraulic Plo are input to supply the high lubrication hydraulic pressure Phi and the low lubrication hydraulic pressure Plo to a second brake B2 while switching them, a regulator valve 43 producing the high lubrication hydraulic pressure Phi by adjusting a pressure of the oil discharged from a mechanical oil pump 34, and a lubrication modulator valve 47 producing the low lubrication hydraulic pressure Plo as a constant pressure lower than the high lubrication hydraulic pressure Phi by adjusting the pressure of the oil discharged from the mechanical oil pump 34. |
