Abstract: An ejector-type refrigeration cycle device is provided with a first ejector (15) which draws refrigerant from a refrigerant suction port (15b, 24b) by using a high-speed refrigerant flow jetted from a nozzle part (15a, 24a), and a first suction-side evaporator (19) connected to the refrigerant suction port (15b) of the first ejector (15), and a second suction-side evaporator (27) connected to a refrigerant suction port (24b) of a second ejector (24). A flow amount of the refrigerant in the second ejector (24) is smaller than a flow amount of the refrigerant in the first ejector (15). The refrigerant branched at a branch part (Z2) that is positioned on a downstream refrigerant side of a radiator (13) and on an upstream refrigerant side of the first ejector (15) flows into the second ejector (24), and the refrigerant branched on a downstream refrigerant side of the second ejector (24) flows into the second suction-side evaporator (27).
