PROBLEM TO BE SOLVED: To solve a problem wherein it is difficult to work a protruded rocking part of a vane accurately in shape accuracy and surface properties such as circularity, cylindricity and surface roughness at low cost. SOLUTION: A cylindrical recessed slide part 56 formed on a roller 104 and the protruded rocking part 57 provided at the roller side of the vane 20 are connected in such a manner that the same can freely rock. One or a plurality of clearances 20a are disposed at the protruded rocking part 57 of the vane 20. The vane having the cylindrical protruded rocking part 57 which is worked accurately in shape accuracy and surface properties such as circularity, cylindricity and surface roughness at low cost is mounted on a compressor. An efficient and reliable low cost rotary compressor is provided thereby. COPYRIGHT: (C)2010,JPO&INPIT
