In a refrigerant cycle device, a radiator has a heat radiating portion for radiating high-pressure refrigerant discharged from a compressor and a refrigerant outlet downstream from the heat radiating portion, an ejector includes a nozzle portion for decompressing and expanding refrigerant and a refrigerant suction port for sucking refrigerant by high-velocity refrigerant flow jetted from the nozzle portion. The refrigerant cycle device includes a throttle unit for decompressing refrigerant flowing out of the refrigerant outlet of the radiator, an evaporator located between a refrigerant downstream side of the throttle unit and the refrigerant suction port of the ejector, and a branch portion located within the heat radiating portion of the radiator to branch a refrigerant flow. In the refrigerant cycle device, the nozzle portion has a nozzle inlet coupled to the branch portion so that refrigerant flows into the nozzle inlet from the branch portion of the radiator.
