る欠点かめる。(b) Prior art In the conventional hermetic rotary compressor described in Japanese Utility Model Application Publication No. 57-71785, which precedes the present invention, the rotary rollers and sliding vanes constituting the rotary compression element are arranged in a large mold plate. Since the vane is made of iron-based rope material, the eccentric force of the rotating shaft increases and large vibrations occur due to deflection of the shaft.The disadvantage is that the rotating shaft is unevenly abutted against the shaft support, causing severe wear. ! This has the disadvantage that the compressor's compression efficiency decreases as the responsiveness deteriorates and the compressor becomes unable to follow the rotation of the rotary roller.

点がある。Furthermore, in the sealed rotary pressure N machine, the abutting surfaces of the rotary row 2 and the sliding vanes are undercoated with a metal film and coated with a ceramic film, but the ceramic film is coated with a ceramic film on the base material. Since both the ceramic film and the undercoating film are made of different materials, the adhesive force at the interface between the ceramic film and the undercoating film is weak.

できる。(G) Effects of the Invention The present invention is constructed as described above, and since the rotating roller and sliding vane are made of an aluminum material, the eccentric force on the rotating shaft is reduced due to the softness and weight reduction compared to iron material. In addition, it is possible to suppress uneven wear and improve the followability of the sliding vane to high-speed rotation of the rotating roller. Also, aluminum vapor deposition and ion implantation are performed on at least one of the contact surfaces between the rotating roller and the sliding vane, Since the hard ceramic film is coated, the interface between the base material and the ceramic film disappears and a mixed layer is created, and the hard ceramic film can be coated in a strong manner without peeling. Even during rotation, the contact surface between the rotating roller and the sliding vane is protected from seizure and peeling of the coating film, thereby providing a rotary pressure M machine with low vibration and high compression efficiency.
