すい欠点がある。2. Description of the Related Art Conventionally, an attachment for an air spray gun of this type has an air nozzle that penetrates the attachment body, and a packing fitted in the gap is tightened with bolts from both sides to seal the paint passage. Since it is formed on the outer circumference of the attachment body, it is difficult to remove the air nozzle, and if the air nozzle or paint passage is clogged, it takes a long time to remove it. Since it is supported by a cantilever, it has a drawback that it is likely to be misaligned with the paint nozzle.
