PURPOSE:To favorably feed oil to a bearing by providing an oil discharge port one end of which is opened in a bearing installed on a frame while the other end is opened in a chamber on the outside of said frame. CONSTITUTION:To feed oil to the plain bearing 8 of a revolving scroll 3, oil in a chamber is introduced to an oil chamber 29 by the centrifugal pumping action of an eccentric oil feeding passage 19. And, the oil lubricate the plain bearing 8 from the oil chamber 20 through an oil feeding groove 21. Oil is fed to a plain bearing 11 via an oil feeding port 26 and an oil feeding passage 27. Thereby, the feeding and discharging of oil to and from each bearing can be favorably carried out, preventing the wear and seizing of the bearings.
