Thereby, the portion of the sliding portion 26J that slides the inner peripheral portion 48D of the insertion hole 48A can be suppressed to be small. Therefore, since the abrasion of the sliding portion 26J is reduced and the life of the sliding portion 26J is extended, the frequency of the maintenance sliding portion 26J is lowered. Therefore, it is possible to improve maintenance.

  • the posture of the rotary nozzle 26 can be naturally corrected by the difference in momentum of these cleaning liquids, so that the inclination of the rotary nozzle 26 can be eliminated. Therefore, it is possible to prevent the rotation of the rotary nozzle 26 from being stagnant due to the inclination of the rotary nozzle 26.
  • the rotary nozzle 26 can be separated into an upper end portion 26A and a main body portion 26B. Therefore, when the upper end portion 26A is clogging a foreign object or the like, and the upper end portion 26A is to be maintained, even if the entire rotary nozzle 26 is not detached from the storage chamber 11, as shown in FIGS. 7A and 7B, only the unloading is performed.
