<P>PROBLEM TO BE SOLVED: To provide a coating material spray nozzle with which a step end face of a step part generated in a portion, whose diameter is reduced step by step, can be coated in a stable state and coating quality can be improved. <P>SOLUTION: This coating material spray nozzle 20 comprises a nozzle body 21, a spray port 22c and a weight part 25. The nozzle body 21 is mounted to a distal end 12b of a coating material supply hose 12 connected to a coating material supply mechanism (airless coater) press-feeding the coating material, and inserted from the upper side into a pipe, whose diameter is reduced step by step toward one end. Furthermore, the spray port 22c is provided in the nozzle body 21 and sprays the coating material toward the side of the coating material supply hose 12. Furthermore, the weight part 25 is positioned lower than the spray port 22c and becomes the center of gravity of the nozzle body 21. <P>COPYRIGHT: (C)2013,JPO&INPIT |
