PROBLEM TO BE SOLVED: To prevent a paint mist included in the atmosphere around a rotary atomization head and a head member from entering an inner circumferential space between the atomization head and the head member.SOLUTION: A head member includes a plurality of shaping air discharge ports 12 and a plurality of second air discharge ports 16, which are formed on a common circumference, the second air discharge ports 16 being disposed at the midpoint each between two adjacent shaping air discharge ports 12, 12. The diameter Dbr of the second air discharge port 16 is smaller than the diameter Dsa of the shaping air discharge port 12, and the amount of air discharged from the second air discharge port 16 is smaller than the amount of shaping air. An air flow discharged from the second air discharge port 16 forms an air barrier to prevent a paint mist from entering an inner circumferential space through a gap between the adjacent shaping air discharge ports 12, 12. |
