A refrigeration cycle device comprising flow path connecting members (50, 51, 55, 56) that configure at least one of either: a branched section and a confluence section for a third refrigerant passage (18); or a branched section and a confluence section for a bypass passage (22). One of three refrigerant ports for the flow path connecting members is directly connected to one of two refrigerant ports for a first switching device (17) and a second switching device (23). Sealing mechanisms (50a, 17a, 58) that prevent refrigerant leakage are provided in the connection section between the refrigerant port for the flow path connection members and the refrigerant port for the first switching device or second switching device. The flow path connection members are fixed to one of the switching devices at a site different from the sealing mechanisms. As a result, vehicle mounting space can be reduced, the number of components can be reduced, cooling and heating performance can be increased, the amount of refrigerant or refrigerator oil enclosed can be reduced, and refrigerant leakage can be suppressed. |
