<；P>；PROBLEM TO BE SOLVED: To provide a water stream oscillating nozzle capable of spouting a liquid widely, and easily fabricating. <；P>；SOLUTION: A flow-in part 2 is connected to a piping through a spherical joint. The flow-in part 2 integrally communicates with a reduced flow path 3 having an inner diameter smaller than that of the flow-in part 2. The reduced flow path 3 is fitted to a fitting part 6 of an end part of a turbulent flow generating part 5 communicating with the flow path 3 and having a spouting hole 4. A turbulent flow generating body 7 is provided in the vicinity of the front end part of the reduced flow path 3 in the turbulent flow generating part 5. In such water stream oscillating nozzle 1, the liquid flows through the reduced flow path 3 from the flow-in part 2, and further in the turbulent flow generating part 5 from the reduced flow path 3. The liquid comes into collision with the turbulent flow generating body 7 to generate a turbulent flow in the liquid, when the liquid flows into the turbulent flow generating part 5 from the reduced flow path 3. The liquid can spout widely by oscillating from the spouting hole 4 by the turbulent flow. <；P>；COPYRIGHT: (C)2009,JPO&INPIT
