摘要： PURPOSE:To provide a sprinkler nozzle which is simple in a structure, capable of injecting waterdrops having small diameter and proper for sprinkling of a field by forming a nozzle hole passing through a nozzle main body and forming the cross section thereof into a three or more sided figure. CONSTITUTION:A nozzle main body 1 is formed of metal or synthetic resin and a nozzle hole 2 through the nozzle main body 1 is provided. The nozzle hole 2 is formed of both a tapered part 3 of a nearly conical shape and a square part 4 respectively described below. The tapered part 3 is formed into a cylindrical shape in the base end side and shrunk toward the tip side until the middle part. The cross section of the square part 4 is formed into a triangle, a quadrilateral or the like to the aperture part of the tip from the tapered part 3. Since disturbance of water flow is easily caused thereby and injected water is splashed to as to be twined to the outside of water stream by air resistance, the nozzle lines are enlarged in comparison with a cross-sectional circle. Waterdrops having small diameter can be injected even at the low water pressure and necessary energy can be reduced.
