PROBLEM TO BE SOLVED: To prevent air and liquid in a piping from mixing with each other and blowing off suddenly when the liquid is ejected from an ejection hole. SOLUTION: A gas-liquid separator 5 is arranged between a piping 11 connecting to an ejection nozzle 4 and a piping 12 connecting to a liquid feed source 6. A pass control means 17 is engaged in a gas-liquid separation room 16 of the gas-liquid separator 5 so that there is play therebetween. A discharge hole 19 for discharging air is formed on the gas-liquid separator 5. When the liquid fed from the liquid feed source 6 flows in the gas liquid separation room 16, the air mixed into the liquid is separated by the pass control means 17, and the air is discharged from the discharge hole 19 to the outside, and the liquid passes from a discharge port 18a through the piping 11 and is ejected from a liquid ejection hole 3 of the ejection nozzle 4. At this time, since the ejected liquid is separated from the air, there is no case that the air blows off suddenly while the air is mixed with the liquid.
