<p>PROBLEM TO BE SOLVED: To provide an artificial rainfall nozzle with which various shapes of artificial rainfall areas are attained and an area of the artificial rainfall can be easily enlarged, and to provide an artificial rainfall device.SOLUTION: An artificial rainfall nozzle 10 used when bringing rain artificially is constructed including a flexible tube part 13C that is connected with a water supply source, formed of a flexible member, and includes a tip opening part 13F from which water is gushed out. A piece of flap-like chip 13E is arranged at the tip opening part 13F of the flexible tube part 13C as turbulence generation means T G in which turbulence of water containing a pulsatile flow is generated from a laminar flow state.</p> |
