Abstract: A spray nozzle member jets out paint in a fan-shaped pattern. Air streams are jetted from a conically annular center air nozzle in such a way as to surround the fan-shaped pattern, whereby a conically atomized spray pattern is discharged from a deformed opening. Notches formed on the deformed opening cause the conical pattern to spread, and fan-shaped air streams produced by air from auxiliary air nozzles promote the spreading of the spray pattern to a greater extent. Oblique air streams are forwardly supplied from side air nozzles into that pattern, so that a fan-shaped spray pattern is again produced. Paint under a pressure of several kg/cm.sup.2 is discharged from a spray nozzle. An atomizing air stream, except the part thereof corresponding to the edge of the fan-shaped spray, converges on the front extremely close to the spray nozzle. The atomizing air stream is discharged under a pressure of less than 2 kg/cm.sup.
