A spray gun in which machining is facilitated by simplifying the nozzle shape and the frequency of replacing a nozzle can be decreased by enhancing durability of the nozzle. A spray nozzle (3) is constituted by being divided into a tubular nozzle main body (5) having a paint supply passage (12) for supplying paint from the paint supply section (2A) of a gun body (2) formed in the central portion to penetrate in the axial direction and having a paint ejection hole (10) formed to open on the distal end side of the paint supply passage (12), and a tubular air guide member (6) being fitted to the outer circumference of the nozzle main body (5). An annular passage (25) for supplying air from the air supply section (2B) of the gun body (2) toward an air ejection hole (11) is formed in the air guide member (6), and that annular passage (25) is formed along the axial direction by the outer circumferential surface of the nozzle main body (5) and the inner circumferential surface of the air guide member (6). |
