The present invention has an object to provide a spray gun having a simplified nozzle shape to facilitate working the nozzle, having an improved nozzle durability, and capable of reducing a nozzle replacement frequency. The spray nozzle(3) is configured so that a coating material supply channel(12) passing a coating material from the coating material supply part (2A) of the gun main body (2) penetrates through a central portion in an axial direction, and so that a cylindrical nozzle main body having the coating material ejection hole (10) formed to be open on a tip end side of the coating material supply channel (12) and a cylindrical air guide member (6) fitted into a surrounding outside of the nozzle main body (5) are separately provided, and an annular air passage(25) supplying air from the air supply part of the gun main body toward the air ejection hole (11) is formed in the air guide member (6), the annular air passage (25) being formed by an outer circumferential surface of the nozzle main body (5) and an inner circumferential surface of the air guide member(6) along the axial direction. |
