PROBLEM TO BE SOLVED: To provide a highly reliable vane rotary compressor by preventing contact of a rotor with a rear side plate when starting the compressor, and suppressing abnormal abrasion. SOLUTION: This compressor having a compression chamber 3a sucking and compressing fluid and a narrow clearance distributing the fluid inside the compressor into a delivery side and a suction side by the rotor 5 provided inside the compressor, is provided with a means 6a ensuring a small clearance between the rotor and the wall of the compression chamber even if the rotor 5 slides when the compression chamber is started. When the compressor is started, the rotor and rear side plate are less likely to be brought into contact with each other, and the abnormal abrasion is suppressed. COPYRIGHT: (C)2009,JPO&INPIT
