PROBLEM TO BE SOLVED: To enable a spray pattern the thickness of whose edge part is thinned down by making a nozzle having an outlet hole of cat's eye type rotated around prescribed axis, which outlet hole has a wide open angle an airless spray tip. SOLUTION: The track motion of an airless spray tip 12 can be obtained by rotating the airless spray tip 12 to a spray gun 11, particularly rotating the airless spray tip 12 around axis which is parallel to the central axis of an outlet hole and is eccentric relative to it. The airless spray tip may be any of the conventional airless spray tips, but that of the so-called cat's eye type in which an outlet hole 16 installed in the domed head part have a pair of planes 18, 18 sectorially opened at an angleαto the central axis is preferable. In particular, the angleαis preferably set at a wide angle, and in this way, the width of a spray pattern can be increased.
