Claims

[Claims for Utility Model Registration] 1. A cylindrical or elliptical hollow portion of the cylinder accommodates a rotor having a vane slidably fitted in a vane groove, and a front side plate and a The rear side plates are joined together, and a suction port and a discharge port are opened in the space surrounded by both side plates, the cylinder, and the rotor, and by rotating the rotor from the outside, the fluid sucked from the suction port is compressed. A vane compressor in which a wear-resistant coating is formed on the outer circumferential surface of the rotor, both end surfaces, and the wall surfaces of the vane grooves, in which the vane compressor discharges from the discharge port. 2. The vane compressor according to claim 1, wherein the wear-resistant coating is made of tetrafluoroethylene resin. 3. The vane compressor according to claim 1, wherein the wear-resistant coating is also formed in the back pressure passage at the inner end of the vane groove.
