To prevent the amount of lubricating oil from becoming uneven in compressors for performing two-stage compression-type refrigerating cycle and to prevent the structure from being complicated.
The refrigerating device includes a refrigerating circuit including a compression mechanism (20) having a low stage side compressor (30) and a high stage side compressor (40). The refrigerating device includes an oil equalizing pipe (51) for equalizing pressure in casings (31, 41) of compressors (30, 40), respectively, and equalizing the amount of lubricating oil stored in the casings (31, 41) of the compressors (30, 40), respectively. In the low stage side compressor (30), a suction pipe (36) and a discharge pipe (37) are directly connected to a compressor part (32). In the high stage side compressor (40), a suction pipe (46) is directly connected to a compressor part (42) and a high pressure refrigerant is directly discharged into the casing (41). The oil equalizing pipe (51) connects the casing (31) of the low stage side compressor (30) and the casing (41) of the high stage side compressor (40).
