Abstract: PROBLEM TO BE SOLVED: To provide a two-stage rotary compressor for preventing a vane from being pushed back to a back face side by a flow of suction gas of intermediate pressure in a high stage compression part of the two-stage rotary compressor. SOLUTION: A gas passage 14 is arranged on the back face side of the vane 12 of the high stage compression part 3, and is communicated with a gas passage 14 via a discharge hole 16 formed in a low stage compressor 2 and a through hole 17 formed in a partition plate 9. Intermediate pressure gas (CO2 refrigerant gas) compressed by the low stage compression part 2 is passed through into the gas passage 14 via the discharge hole 16 and the through hole 17. The passed gas passes through outside from a through hole 15 arranged in a cylinder 3a. The vane 12 is pressurized on the back face side by the intermediate pressure gas passing through into the gas passage 14, and always abuts to the outer periphery of an eccentrically rotating roller 3b by a force not less than the pressing force of a spring 13. An almost triangular projection 12a is arranged on the back face side of the vane 12, and gas pressure is efficiently received by projecting the projection 12a in the gas passage 14.
