流ポンプ。[Claims for Utility Model Registration] (1) A main side fluid introduction path that is communicatively connected to the main side fluid feed pipe, a nozzle that injects the main side fluid introduced into the main side fluid introduction path, and a sub a sub-side fluid introduction path that communicates with the side fluid feed pipe; and a main fluid introduction path that sucks the sub-side fluid introduced into the sub-side fluid introduction path by jetting the main-side fluid and that is injected from the nozzle. In a jet pump equipped with a diffuser having a fluid discharge port for discharging side fluid and sucked sub-side fluid, an inner wall of either the main side fluid introduction path or the sub-side fluid introduction path has an inner wall. A jet pump characterized in that at least one abutting protrusion is provided that protrudes toward the circumference and abuts the fluid feed pipe. (2) The jet pump according to claim (1), wherein the inner diameter dimension of the main side fluid introduction passage is different from the inner diameter dimension of the sub side fluid introduction passage. (3) The length dimension of the connection part of the main side fluid introduction path that communicates and connects to the main side fluid supply pipe is the length dimension of the connection part of the sub side fluid introduction path that communicates and connects to the sub side fluid supply pipe. The jet pump according to claim (1), which is different from the jet pump.
