Claims

[Claims for Utility Model Registration] A cylindrical cylinder space is formed in the housing body, and a cylindrical rotor body having a diameter smaller than the diameter of the cylinder space contacts the cylinder space eccentrically or concentrically at one or two places. The vane is rotatably housed in the rotor body, and the vane is fitted in a protruding manner into one or more vane grooves bored in the rotor body, and the tip of the vane is slid along the cylinder wall as the rotor body rotates. In a vane compressor that compresses working gas in the working chamber by changing the volume of a working chamber partitioned by vanes, the cylinder wall has a diameter that is the same as the diameter of the rotor main body at the contact portion between the cylinder wall and the rotor main body. An airtight maintenance mechanism for a vane-type rotary compressor, characterized in that the concave portion has a curved surface, and the outer circumferential surface of a rotor body is superimposed over a predetermined length on the curved surface.
