A rotary compressor includes a cylinder, a piston, and a pair of bushes (45a and 45b) which sandwich a blade (35) integrally formed with the cylinder to support the blade (35). At least one of the pair of bushes (45a and 45b) includes an oil supply passage (1) formed from a flat side surface (7) to a curved side surface (6) of the bush (45a, 45b), a blade-side oil reservoir (2) formed on the flat side surface (7) such that one end of the oil supply passage (1) is open to the blade-side oil reservoir (2), and a groove-side oil reservoir (3) formed on the curved side surface (6) of the bush (45a, 45b) such that the other end of the oil supply passage (1) is open to the groove-side oil reservoir (3). The groove-side oil reservoir (3) is wider than the blade-side oil reservoir (2). |
