PURPOSE: To keep the beautiful view and extend the maintenance period and lower the maintenance cost by composing a water jetting nozzle using an outer cylinder to which water is supplied from the bottom, a cover which has a through hole in the center part and covers the upper part of the outer cylinder, and an inner cylinder which penetrates the through hole of the cover and has a sliding body in the lower part.

CONSTITUTION: When pressured water is supplied to a lower part metal fitting 3 of a water jetting nozzle, an inner cylinder 5 goes up due to the water pressure applied to a sliding body 6 and the inner cylinder 5. At that time, water between the inner and an outer cylinders 5, 1 is released out of a water passing hole 8. Due to the rise of the inner cylinder 5, the tip part of a nozzle piece 7 comes out of the water surface 10, and simultaneously, pressured water is jetted out from the tip part. A rectifier 9 is inserted in the inside of the nozzle piece 7 to prevent the disorder of the water flow. A jet of water with various kinds of shapes is formed by changing the shape of the nozzle piece 7. When the supply of the pressured water is stopped and the water pressure is lowered, the inner cylinder 5 falls in the inside of the outer cylinder 1 and the nozzle piece 7 goes under the water surface 10 and the jetting nozzle is hardly seen from the diagonal direction above the water surface.
