PURPOSE: A lubricating oil supply device is provided to lengthen the time for maintaining a normal state after starting even without increasing the capacity of a solenoid and to reduce power consumption. CONSTITUTION: A lubricating oil supply device(S) comprises a motor pump(1) supplying the lubricating oil reserved in a pressure-released pipe(Pt) and a pressure-retained pipe(Ps), a lubricating oil storing part(2) storing the lubricating oil, a solenoid valve(10) installed in the supply path of the lubricating oil from the motor pump and changing the state of the supply path by starting and stopping a solenoid(11), and a power supply controller(20) controlling the power supply voltage supplied to start the electronic solenoid of the solenoid valve.
