PROBLEM TO BE SOLVED: To secure a clear visual field through an observation window after feeding water and gas by a simple structure.
SOLUTION: A surface tension destroying part 201 as a means for destroying the surface tension, a characteristic structure in this embodiment, for reducing the size of a droplet attached to the observation window 154 when water is fed to a prescribed diameter or smaller, is disposed in a sidewall distal end area 200 located on the sidewall end, a region facing at least an opening 162 of a nozzle 164, in a distal end face 150A of the distal end 150. The surface tension destroying part 201 is composed of a plurality of grooves 202 formed as straight lines of a prescribed length and radially around the center point A of the opening 162 of the nozzle 164.
