PROBLEM TO BE SOLVED: To provide a rotary compressor having a constitution capable of restraining an increase in an abrasion quantity of a bush hole inner wall surface for arranging a blade bush provided in a cylinder. SOLUTION: The blade bush 22A has a cross-sectional shape including a first side surface 221 abutting on a blade 21, a second side surface 222 positioned on the cylinder chamber 11 side and extending in the substantially vertical direction from the blade, a third side surface 223 opposed to this second side surface 222 and positioned on the side going away from a cylinder chamber 11, and a fourth side surface 224 of a curved surface shape opposed to the first side surface 221 and contacting with a side surface of the cylinder for regulating a bush hole. A curved surface (the corner R) having a radius of 0.1 mm or more, is also arranged in a corner part C1 where the second side surface 222 intersects with the fourth side surface 224.
