A nozzle structure of a cutting oil injection device is provided to keep a close contact of an injection nozzle and a turret for preventing infiltration of a chip when the turret rotates to change a tool by installing a scraper at an outer periphery of the receiving unit of the injection nozzle. A nozzle structure of a cutting oil injection device, including a cutting oil piston(121) installed inside a cutting oil injection block(120), to control a flow of the cutting oil, and an injection nozzle(123) installed to communicate with a cutting oil inflow port(122) when clamping of a turret(130), comprises the followings: a receiving unit(124) formed by cutting an outer periphery of the injection nozzle at one end; a scraper(125) installed at an outer periphery of the receiving unit, to be slid at a regular distance; and a scraper spring(127) installed at a connecting space of the receiving unit and the scraper. The scraper is bended in a regular gradient to form a protrusion part(125a) contacted closely to the turret.
