PROBLEM TO BE SOLVED: To provide a lubricating oil supplying device having a small volume at a low cost to supply a lubricating oil from a lubricating oil distributing valve selected according to a lubricating oil supply position of an injection molding machine. SOLUTION: The lubricating oil supplying device comprises a tank 4 for storing the lubricating oil, a lubricating oil pump 2 connected at a suction side to the tank 4, a motor 3 for driving the pump 2, a controller 9 for controlling the motor 3, and a switching valve 5 connected to a discharge side of the pump 2. In this case, at least one advancing type lubricating oil distribution valve 6 for distributing the oil to a plurality of oil supply positions, and at least one parallel type lubricating oil distribution valve 7, are selectively connected to the discharge side of the pump 2 by the valve 5. Accordingly, an optimum combination of the valve 6 and the valve 7 is made corresponding to the oil supply position, and the supply device can be reduced in size and cost.
