CONSTITUTION: A cooling device for cooling a driving motor for a hybrid vehicle comprises an electric oil pump(30), a switching valve(60), a solenoid valve(40), and a control unit. The electric oil pump generates hydraulic pressure for cooling the driving motor(50) of a hybrid vehicle. The switching valve transfers the hydraulic pressure generated by the electric oil pump to the driving motor selectively. The solenoid valve switches an inner passage of the switching valve through supplying control pressure to the switching valve selectively. The control unit operates or stops the electric oil pump by first, second, or third step workload according to the temperature of a driving motor or turns on or off the solenoid valve.
