An apparatus for spraying oil uniformly is provided to rapidly increase coating quality of oil by applying oil from the spray nozzles onto a surface of an oil coating roll through a compressed ejection type oil supply process while alternately moving spray nozzles side to side. An apparatus for spraying oil uniformly comprises: a fixed frame for rotatably supporting both sides of an oil coating roll; one pairs of racks(130), screw shafts(110) and guide bars(120) sequentially installed in the vertical direction and idly fixed to the fixed frame by means of bearings in the length direction of the fixed frame; a drive motor connected to one end of one of the screw shafts and installed on the fixed frame; a driven shaft idly which is installed on the fixed frame and has drive and driven bevel gears engaged with each other to connect the one pair of screw shafts; spray nozzle bodies(300) having pinions(230) fixed to front ends thereof such that the pinions are rotatable geared with the racks, screw connectors(210) formed on intermediate portions of outer peripheral surfaces thereof such that the screw connectors are engaged with the screw shafts, and guide rings(220) formed on lower portions of the outer peripheral surfaces thereof such that the guide bars are inserted into the guide rings; spray nozzles(310) fixed through the pinions; an oil supply pipe connected to oil channels formed in the pinions and the spray nozzle bodies; touch elements(506) fixed to portions of the spray nozzle bodies; and limit switches(180) which are formed on the fixed frame and come in contact with the touch elements to control the rotation direction of the drive motor.
