PROBLEM TO BE SOLVED: To solve problems that the conventional air combination type airless gun operated by mixing atomizing air with a pressurized coating material jetted from a nozzle chip outside a nozzle chip is insufficient to eliminate the atomizing defect and the front surface or the like of an air cap is easily soiled due to the return of the coating material. SOLUTION: In a rotary chip type, air jetting ports 25 for atomizing are arranged just beside right and left with the interposed nozzle chip 11 having a long elliptic pattern and face to strike the atomizing air against each other near a coating material jetting port 11c of the nozzle chip 11. Then, the coating material jetted from the nozzle chip 11 receives the collision energy of the atomizing air from the initial time of the jetting to uniformly atomize the coating material over the whole jetting pattern to prevent the generation of tail. Because there is no room to produce a problem that the atomizing air flow strikes the particle of the coating material, the return or the scattering of the coating material is suppressed to prevent the soiling.
