Beschreibung
Zusammenfassung:	In an ejector, a passage formation member is disposed inside a body forming a space therein. Provided between an inner peripheral surface of the body and the passage formation member are a nozzle passage functioning as a nozzle, a mixing passage in which an ejection refrigerant ejected from the nozzle passage and a suction refrigerant drawn through a suction passage are mixed together, and a diffuser passage that converts a kinetic energy of the refrigerant that has flowed out of the mixing passage into a pressure energy. The mixing passage has a shape gradually reducing in cross-sectional area toward a downstream side in the refrigerant flow.
