PROBLEM TO BE SOLVED: To efficiently clean smudge or the like of a nozzle having a sliding part.SOLUTION: An operator inputs a nozzle cleaning device 10 in an ultrasonic cleaning tank 70 with a cleaning liquid therein, and turns on a switch of the ultrasonic cleaning tank 70 to provide ultrasonic vibration to the cleaning liquid, and also turns on a switch of a drive motor 52 of the nozzle cleaning device 10 to vertically move a pressing member 60. When the pressing member 60 moves downward, a cartridge 30 and an upper cover 40, which hold a nozzle support body 86, move downward with respect to the nozzle main body 82 against elastic force of a spring 24. When the pressing member 60 moves upward, the cartridge 30 and the upper cover 40, which hold the nozzle support body 86, are biased upward by the elastic force of the spring 24, and thus move upward with respect to the nozzle main body 82.SELECTED DRAWING: Figure 1 |
