Claims (1)

[Claims for Utility Model Registration] 1. A rotor that is eccentrically inserted into a housing, and a plurality of vanes that are fitted into the rotor so as to be freely protrusive and retractable in the radial direction and partition a space between the housing and the rotor in the circumferential direction. A vane-type rotary compressor, characterized in that a large number of grooves are formed on both end surfaces of the vane facing the inner wall surfaces at both ends of the housing so as to extend toward the outer diameter side so as to be inclined forward in the counter-rotation direction. Vane type rotary compressor. 2. The vane type rotary compressor according to claim 1, wherein the groove extends over the entire width of both end faces of the vane. 3. A vane-type rotary compressor according to claim 1, wherein the groove is in the shape of a dead end extending from the front edge in the rotational direction of both end faces of the vane to a halfway point.
