PROBLEM TO BE SOLVED: To provide a further suitable rotary compressor for improving energy efficiency by restraining a pressure variation generated in a delivery space of an intermediate vessel. SOLUTION: This rotary compressor 1 has a rotary type low pressure side compression part 10 compressing a refrigerant, a rotary type high pressure side compression part 12 compressing the refrigerant in an opposite phase to a compression process of the low pressure side compression part 10 and the intermediate vessel 18 communicated with a refrigerant delivery port 14 of the low pressure side compression part 10 and a refrigerant suction port 16 of the high pressure side compression part 12. The intermediate vessel 18 is constituted so that the inside delivery space 20 is partitioned into a main flow side space 20a and an anti-main flow side space 20b by a partition member 22, and the refrigerant delivery port 14 of the low pressure side compression part 10 and the refrigerant suction port 16 of the high pressure side compression part 12 are communicated with the main flow side space 20a, and a refrigerant flow passage 20c for connecting the main flow side space 20a and the anti-main flow side space 20b is formed in the partition member 22.
