A gas compressor includes a cylinder block, a rear side block, a front side block, a cylinder chamber segmented by the above three blocks, a rotor provided in the cylinder chamber, vane slots formed on the rotor, vanes inserted into the vane slots, and a suction hole provided on at least one of the front and rear side blocks. Refrigerant is suctioned into the cylinder chamber from the suction hole. An opening edge of the suction hole is composed of an in-chamber opening edge that locates within the cylinder chamber and an in-block opening edge that faces to a sidewall of the cylinder block. The in-chamber opening edge locates on a side of an oval inner wall away from an outer circumference of the rotor. According to the gas compressor, leaning of the vanes is restrained, so that ground damage or attrition of the blocks, vibrations and noises are restrained.
