PURPOSE:To permit easy replacement of nozzle members and change of a spray shape by coupling the upper and lower annular nozzle members by screwing so that the positional relation of the two nozzles is made freely adjustable and coupling a spray adjusting ring by screwing to the inside of the upper nozzle. CONSTITUTION:The lower annular nozzle member 34 is pressed by a retaining member 38 to a frame body 31. The retaining member 38 is fixed to the frame body 31 by a fixing means 39. The upper annular nozzle member 36 is fitted to the lower annular nozzle member 34 and is so disposed as to be screwed down by a screw 50. The spacing of a slit 40 for ejecting liquid is adjusted by adjusting the screwing-down amt. of the upper annular nozzle member 36. The spray adjusting ring 36a is engaged by screwing concentrically with the inside of the upper annular nozzle member 36. The nozzle shape is changed by changing the shape at the top end 36b of the ring 36a to adjust the spray shape as desired. The two nozzle members 34, 36 can be easily replaced simply by removing the retaining member 38.
