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.
