PROBLEM TO BE SOLVED: To provide a fluid injection nozzle which can improve washing efficiency while changing an injection direction of fluid every moment without changing an intended direction while suppressing diffusion of fluid upon injection.SOLUTION: A nozzle body 30 arranged revolvably and rotatably in a chamber CH which makes fluid introduced to an inner part via a first fluid introduction hole 25A and a second fluid introduction hole 25B disposed on a circumferential surface vortex flow is provided. The nozzle body 30 has an inflow port 32a to which the fluid in a chamber CH flows in and an injection port 32b which injects the fluid and, further, has a flow channel 32 through which the fluid flows, a contacting part 31e which is formed on a circumference of the injection port 32b and is brought into spherical contact with an inner side end part 22e of a circular nozzle hole 22c disposed on an end part of the chamber CH and a distributor 33 which suppresses revolution of the fluid in the flow channel 32.SELECTED DRAWING: Figure 1 |
