PURPOSE:To simplify construction of a flow path and to promote stabilized action or the like, by providing a jet stream injecting supply nozzle, inducing chamber having an opening communicating with the atmosphere and a side wall so that deflecting oscillation of a jet stream is performed with out providing a feedback flow path. CONSTITUTION:Inflow fluid to a supply flow path 6 is injected from a supply nozzle 7, and this jet stream Fil becomes a high speed flow in an inducing chamber 8, causing it to generate a pressure not more than the atmospheric pressure. As a result, air, which passes through a gas introducing port 9, is induced into the inducing chamber 8, and gas vortexes VL1, VR1 are formed in both sides of the jet stream Fil. Here the jet stream Fil, if its upper side gas vortex VL1 low decreases the pressure, is previously deflected to an upper side being jetted from a jet port as a stream FO1. Next, on part of a gas vortex VL2, formed by a jet stream Fi2, is allowed to flow out from the inducing chamber 8 as a bubble B, and its inflow to a part of low pressure vortex AL2 destructs a low pressure condition between the jet stream Fi2 and a side wall 11. As a result, the jet stream Fi2, which straight advances as a jet stream FO2, is jetted from the jet port.
