置。[Claim for Utility Model Registration] A rotor body is rotatably housed eccentrically or concentrically in a cylindrical cylinder chamber, and the vanes are fitted in one or more vane grooves drilled in the rotor body so as to be able to protrude. In a vane type compressor, the tip of the vane slides along the cylinder wall as the rotor body rotates, changing the volume of the working chamber divided by the vane to compress the working gas in the working chamber. The base is widened, a holder is housed in the base, and the rear end of the vane comes into contact with the holder, and the holder is urged outward by a spring body made of a shape memory alloy that regains its shape by expanding in a zero-temperature atmosphere below a predetermined temperature. A vane extrusion device for a vane type rotary compressor.
