Abstract
An interior of a nozzle in an ejector is formed with a swirling space in which a refrigerant swirls, and a refrigerant passage in which the refrigerant that has flowed from the swirling space is depressurized. The refrigerant passage includes a minimum passage area part most reduced in the refrigerant passage area, and a divergent part that gradually enlarges in the refrigerant passage area from the minimum passage area part toward a refrigerant ejection port. Plate members, which reduce a velocity component of the refrigerant flowing into the minimum passage area part in a swirling direction, are disposed within the refrigerant passage.
