To prevent each vane as much as possible from jumping up, even in a case of a compressor employing carbon dioxide as cooling medium.
In this rotary compressor, a compression space is formed in the inside of a cylinder 14 and the like, with the cylinder 14 and the like of which openings are blocked at both the ends, a roller 18 and the like, which is rotated in the inside of the cylinder 14 and the like, and a vane 20 and the like, partitioning the space into a high pressure side, and a low pressure side, and the roller 18 form a rotary compression element and refrigerant is sucked to compress by the rotary compression element so as to be discharged out. In this case, carbon dioxide is used as refrigerant, and concurrently, the high pressure side of the vane 20 and the like are made perpendicular.
