PROBLEM TO BE SOLVED: To provide a rotor structure of gas turbine compressor solving problems that a nut is naturally rotated and a looseness is generated and a tightening force of a stacking bolt is lowered when a rotor is continuously rotated and in order to prevent this phenomenon, since a weight and a volume of the nut are increased, a centrifugal force applied to the nut is increased and a large load is applied to the stacking bolt. SOLUTION: An aperture is provided so as to be perpendicular from a side surface facing to a gas passage of a rotor to a stacking bolt aperture. A nut having a dimension capable of being inserted to the aperture and not freely rotating at the inside of the aperture is dropped off to fix the stacking bolt. Thereby, the problem is solved.
