An ejector-type refrigerant cycle device includes: a first evaporator 15 that evaporates refrigerant flowing out of an ejector 14 ; a branch passage 17 that branches a flow of refrigerant between a radiator 13 and the ejector 14 and guides this flow of refrigerant to a vapor-phase refrigerant suction port 14 c of the ejector 14 ; a throttling mechanism 18 disposed in the branch passage 17 ; and a second evaporator 19 disposed downstream of the throttling mechanism 18 with respect to the flow of refrigerant. The throttling mechanism 18 is constructed to be provided with a fully opening function, and to fully open the branch passage 17 when the second evaporator 19 is defrosted. Therefore, in an ejector-type refrigerant cycle device including multiple evaporators, the function of defrosting the evaporators can be carried out with a simple construction.
