Abstract: A spray gun including: a nozzle provided with a fixed-side restricting section; a needle valve inserted inside the nozzle and provided with a valve portion such that an aperture is formed radially therebetween; an elastic seal member that comes in contact and is elastically deformed in an axial direction between the nozzle and the needle valve; and a straight joint formed by a female joint provided on a nozzle hole of the nozzle and a male joint provided on the valve portion. The straight joint is arranged such that the male joint fits inside the female joint before the elastic seal member comes in contact between the nozzle and the needle valve as well as after the aperture becomes the smallest, and the jointed state is retained until the elastic seal member comes in contact and is elastically deformed therebetween.
