Abstract
A spray gun () forms a desired spray pattern by atomizing by means of atomizing air (A) a spray liquid which is sprayed from a liquid ejection port () opened/closed by a needle valve (), and jetting pattern air (P) to the flow of spray mist of the atomized spray liquid. A nozzle taper angle (θ) is set in a range of 5° to 15°, and a cap taper angle (θ) is set in a range of 20° to 40°. Atomizing air (A) is jetted from a nozzle insertion hole () toward the center of a nozzle (). Pattern air (P) is jetted in a spreading suppressed region (R) wherein the flow of the spray mist does not spread over an area greater than or equal to a predetermined cross-sectional area, to the flow of spray mist, and as a result, the spray mist is more uniformly sprayed over a wide range.
