PROBLEM TO BE SOLVED: To provide a gas compressor with improved vane projectability at the start of the compressor. SOLUTION: There is provided a communication passage 21 communicating a high pressure supplying hole 10 with a flat groove 11 at the start of the compressor. High pressure refrigerant gas discharged into the high pressure supplying hole 10 at the start of the compressor is supplied to the flat groove 11, thereby supplying the refrigerant gas to vane groove bottom portions 16a, and improving the projectability of the vanes 17.
