<P>PROBLEM TO BE SOLVED: To improve compressor efficiency and reliability, by relieving boundary abrasion between a discharge side corner part of a vane back face and a vane groove of a cylinder, since a shape and the surface roughness are not specified on the vane groove of a mating cylinder only by paying attention to the surface roughness of a side surface of a suction side of a vane, and since the surface roughness of a certain degree is secured by generally polishing a vane side surface, in a conventional constitution. Ž<P>SOLUTION: A sliding loss of the vane can be reduced by being characterized by applying round-chamfering to the discharge side corner part Rb of the vane back face.
