<p>PROBLEM TO BE SOLVED: To provide a rotary atomization type coating device capable of improving coating efficiency.SOLUTION: In principle, a coating material flowing out from a coating material outflow hole 23, after being discharged from an outer edge 24a of an inside surface 24, is shaped by airflow from an internal shaping air jetting hole 26 to be sprayed onto a coated object. Out of the coating material flowing along the inside surface 24, a coating material having a large particle diameter bursts through the air from the internal shaping air jetting hole 26 to arrive at an outside surface 27. The bursting coating material is imparted with centrifugal force at the outside surface 27 in order to be sprayed from an outer edge 27a of the outside surface 27 onto the coated object.</p> |
