摘要

PURPOSE:To decrease loss of a coating and loss of a cleaning solvent caused by cleaning at the time of color change and reduce the cost of coating by mount alternatively a plurality of capillary nozzles in a tubular rotating shaft of an air motor with a limited inner diameter. CONSTITUTION:A plurality of capillary nozzles N0-N6 which can be mounted in a tubular rotating shaft 4 of an air motor 3 from the rear end side of the shaft under uncontacting condition are provided with a specified arrangement where the nozzles can be alternatively inserted and released in the tubular rotating shaft 4 and a needle valve 7 which opens and closes a nozzle hole 6 is provided in each nozzle N0-N6 and valve driving parts S0-S6 which open and close the needle valves 7 are provided on the rear end part side and connecting holes P0-P6 connected with a coating hose feeding a coating with a required color are formed.
