PROBLEM TO BE SOLVED: To provide an oil supply device for lubricating oil, in which the air pressure method is employed for pumping lubricating oil to eliminate restriction in oil supply quantity, oil supply positions, and oil supply fall, so that constant oil supply is possible, addition or changing can be freely performed, and maintenance can be omitted. SOLUTION: An oil pumping unit 11 for lubricating oil A is formed by connecting a supply tube 16 for pressure air and a takeout tube 17 for the lubricating oil A to an oil tank 14 containing the lubricating oil A inside. Pressure air is supplied from the supply tube 16 into the oil tank 14, so that the lubricating oil A is pushed by air pressure to be fed from the takeout tube 17 to supply oil piping 12.
