PROBLEM TO BE SOLVED: To exhibit excellent spray precision through a long period by increasing the attaching precision of a coating liquid nozzle while keeping excellent corrosion resistance. SOLUTION: An automatic spray gun is provided with a body 2 having a front opening part, a coating liquid nozzle 3 fitted to the front opening part and having a center hole 3A formed to have coating liquid discharge port 3A1 at the tip, and an air cap 5 having a circular air discharge port 5A1 formed around the tip. The body includes a front body part 7 which has the front opening part and in which an air supply path 20B communicating with the air discharge port 5A1 is formed, a rear body part 9 in which an operation means for a needle valve operation to open and close the coating liquid discharge port 3A1 is housed, and a middle body part 8 which is arranged between them and in which a coating liquid supply path 21 communicating with a center hole is formed. The coating liquid nozzle 3 comprises a coating liquid nozzle body 23 and a metal made outside holding body 25. The air cap, the coating nozzle body and the middle body part are formed from a non-metallic material having corrosion resistance to the coating liquid. COPYRIGHT: (C)2010,JPO&INPIT |
