PROBLEM TO BE SOLVED: To provide a refrigerating cycle for a vehicle in which a cost required for the piping joint of a partition wall passing-through part can be lowered and refrigerant passing sound can be suppressed. SOLUTION: A refrigrant is supplied to an expansion valve 2 from a partition wall passing-through part through a high pressure refrigerant supply piping 3, and the refrigerant is supplied to an evaporator 1 from the expansion valve 2 through a low pressure refrigerant supply piping 4. Thus, the expansion valve 2 is separated from the evaporator 1 by the low pressure refrigerant supply piping 4, so that refrigerant passing sound can be reduced. Further, since the high pressure refrigerant supply piping 3 and a refrigerant return piping 5 are guided to the partition wall passing through part, quick joints 3' and 5" can be used for the piping joint of the passing-through part, and a cost required for the joints can be suppressed to be low.
