Abstract: A rotary atomizing head includes an outer peripheral surface washing passage open onto an atomizing head outer peripheral surface for causing wash fluid supplied from a feed tube to flow out into an annular clearance between the rotary atomizing head and a shaping air ring. An outflow opening of an outflow passage constituting the outer peripheral surface washing passage is provided in a position closer to the backside into the annular clearance by a length dimension than a front end surface of a front ring section constituting the shaping air ring. Further, the outflow opening opens to the annular clearance in an angle that is an acute angle to the atomizing head outer peripheral surface.

Abstract: The durability of resin components can be improved by preventing ozone from staying in gaps where there is no air flow. A cylindrical gap is provided around the outer peripheral side of the head portion between the head portion and the resin cover portion covering the outer peripheral side of the head portion. Moreover, the head portion is provided with a pilot air introduction path guiding the pilot air exhausted from the switching valves to the cylindrical gap. In addition, the arm portion is provided with a pilot air exhaust path exhausting the pilot air from the cylindrical gap to the outside.

Abstract: The present application is related to reducing the paint left inside the piping of the painting device. More specifically the present application is directed to a painting device that includes: a paint output part for outputting paint towards an object to be painted; a paint piping for the paint to pass through towards the paint output part; and a steel ball provided inside the paint piping; and a paint supply part supplying the paint to the paint piping from a side opposite to the paint output part. After the paint supply part stops supplying of the paint, the steel ball moves inside the paint piping towards the paint output part while the paint output part outputs the paint towards the object to be painted. The first moving fluid causes the steel ball to move inside the paint piping towards the paint output part by pushing the steel ball.
