PROBLEM TO BE SOLVED: To enable spray-coating of an adhesive from a short distance favorably on the inside surface of a cylindrical object in spray-coating a liquid formulation such as adhesive from a spray gun. SOLUTION: The subject auxiliary device 16 to be attached to the spray gun is provided with a spray nozzle 14 having a liquid-formulation-jetting port 30 and an atomized-air-jetting port 32. In the auxiliary device 16, air-jet stream is discharged from the outside of the nozzle 14 in the orthogonal direction to the axis of the nozzle 14 to the air-jet stream containing liquid-formulation particles and air discharged from the nozzle 14. The direction of the air-jet stream discharged from the nozzle 14 is changed by blowing side air entirely in the orthogonal direction to the axis of the nozzle. COPYRIGHT: (C)2005,JPO&NCIPI
