PROBLEM TO BE SOLVED: To provide an improvement of cooling performance with two evaporators 15, 18 in an ejector cycle that cools a common space to be cooled by combining the evaporator 15 located downstream of the ejector and the evaporator 18 located at the suction side of the ejector. SOLUTION: The ejector cycle includes the first evaporator 15 connected downstream of the ejector 14 and the second evaporator 18 connected to the refrigerant suction inlet 14b, wherein the refrigerant evaporation temperature of the second evaporator 18 is set at a lower temperature compared to the refrigerant evaporation temperature of the first evaporator 15. The common cooling space 21 is cooled by the first and second evaporator 15, 18, and the first evaporator 15 is disposed upstream side of the cooled air stream direction A and the second evaporator 18 is disposed downstream side of the cooled air stream direction A.
