<p>PROBLEM TO BE SOLVED: To suppress outflow of oil contained in oil mist through a flow passage formed on the immediately downstream side of a mist nozzle.SOLUTION: A mist nozzle 20 is provided for supplying oil mist 7 in which atomized oil floats to the downstream side as the lubricating target part side. The mist nozzle 20 includes a nozzle body part 21 having a jetting port 22, and a cylindrical enlarged cylinder part 26 extended from the nozzle body part 21 to the downstream side. The enlarged cylinder part 26 has an enlarged space 27 greater than an opening cross section of the jetting port 22 on an inner peripheral side. The air jetted from the injection port 22 together with the oil mist 7 is made to generate an eddy current in the enlarged space 27, and the oil contained in the oil mist 7 is gathered in the jetting port 22 by the eddy current, and the gathered oil is splashed to the lubricating target part side by the air jetted from the jetting port 22.</p> |
