Summary:PROBLEM TO BE SOLVED: To provide a rotary compressor in which its vane spring can be fixed certainly to a vane spring mounting hole, this vane spring can be easily mounted on the vane spring mounting hole, and no additional new functional component is needed to fix the vane spring to the vane spring mounting hole.SOLUTION: In part of the vane spring mounting hole 80, there is provided a diameter enlarged portion 81 whose diameter is made larger than that of the vane spring mounting hole. Then, by fitting a large-diameter spring portion 52 of the vane spring 50 into the diameter enlarged portion 81, the vane spring 50 is held fixedly to the vane spring mounting hole 80. A step 85 produced by forming the diameter enlarged portion 81 is allowed to fall within 10 to 50% of a wire diameter of the vane spring 50.
