Abstract: An approximately conical passage-forming member is disposed inside a body in which a swirling space for swirling a refrigerant is formed, and an ejector defines therein a nozzle passage that functions as a nozzle for depressurizing a refrigerant that has flowed out from the swirling space between an inner circumferential surface of the body and the passage-forming member, and a diffuser passage that pressurizes a mixed refrigerant obtained from a refrigerant sprayed from the nozzle passage and a refrigerant drawn from a suction-passage. A plurality of driving passages through which a refrigerant is introduced from a distribution space to the swirling space are formed in the body.
