An exemplary gas turbine includes a rotor unit, a tie-bolt, a cooling air pipe, and a clamping member. The rotor unit includes rotor blades and rotor disks. The rotor blades are arranged on outer circumferential surfaces of the rotor blades. The tie-bolt extends along the central axis of the rotor unit through the rotor disks and fastens the rotor disks. The cooling air pipe has the tie-bolt arranged therethrough and forms a ring-shaped cooling air flow path in an internal space thereof with the tie-bolt through which a cooling air is passed. The clamping member is arranged in the ring-shaped cooling air flow path so as to support the tie-bolt with respect to the cooling air pipe. |
