PROBLEM TO BE SOLVED: To improve lubricating performance and reduce sliding resistance at a sliding part of a compressor mechanism of a rotary compressor. SOLUTION: Since a substantially spherical shot is injected on respective sliding surfaces of an upper bearing 8, a lower bearing 9, a crank pin 4 and a crankshaft 5 as components of the compressor mechanism of the rotary compressor to form recesses with a diameter of 0.1 to 10μm, an oil film is formed by the very small recesses. Since the recesses are discontinuous, the oil retention property of the respective sliding surfaces is increased. The lubricating performance is thus increased, so that the sliding resistance is reduced. COPYRIGHT: (C)2005,JPO&NCIPI
