An ejector refrigeration cycle includes an upstream-side branch portion for branching a flow of a refrigerant flowing out a radiator, an upstream-side ejector having an upstream-side nozzle for decompressing one of the refrigerants branched by the upstream-side branch portion, and a gas-liquid separator for separating the refrigerant flowing out the upstream-side ejector into gas and liquid phase refrigerants. The liquid-phase refrigerant flowing out of the gas-liquid separator is decompressed by a low-pressure side fixed throttle and allowed to evaporate at a first evaporator. The other refrigerant branched by the upstream-side branch portion is decompressed by a high-pressure side fixed throttle and allowed to evaporate at a second evaporator. A merging portion merges the refrigerant flowing out of the first evaporator with the refrigerant flowing out of the second evaporator, so that the merged refrigerant is sucked from an upstream-side refrigerant suction port of the upstream-side ejector.
