PROBLEM TO BE SOLVED: To prevent the inner cylinder member of an oil separator from dropping from a main body member without adding any parts and processes, in a gas compressor. SOLUTION: A cyclone block 70 is provided with the main body member 71 having a substantially cylindrical space 71d and a substantially cylindrical inner cylinder member 72 inserted from an opening 71e in the main body member 71 in a direction (M) along a direction of a substantially cylindrical shaft C1. In a state that the main body member 71 is assembled to a compressor main body 60 by a fastening member 78, a through-hole 71f for arranging the fastening member 78 through the main body member 71 is formed so that a head part 78a of the fastening member 78 is positioned on a virtual trajectory line 72d of an end edge part 72c at an opening 71e side of the main body member 71 in the inner cylinder member 72 in a direction that the inner cylinder member 72 escapes out through the opening 71e of the main body member 71 (in a direction of an arrow N (an opposite direction of an arrow M)) and near the end edge part 72c.
