PROBLEM TO BE SOLVED: To provide a seal structure capable of preventing the leakage of a cooling steam by increasing a sealability between the inside of a rotor and the gas path of a turbine section and coping with the non-uniformity of temperature distribution between rotor disks in a steam cooling type gas turbine. SOLUTION: This gas turbine having the plurality of rotor disks arranged parallel with each other in the axial direction comprises a pair of annular disk lands extended oppositely to each other between the adjacent rotor disks, a pair of annular connection members connected to the disk lands, a pair of annular seal ring pedestals formed integrally with the connection members, and seal rings disposed on the radial inside of the pair of seal ring pedestals.
