Beschreibung
Zusammenfassung:	This gas turbine disassembling/assembling method is configured such that a gas turbine is provided with: a seal plate (44) that is provided to one side in an axial direction with respect to a rotor disk (18); and a seal plate movement restriction part (46) that restricts radial movement of the seal plate (44) with respect to the rotor disk (18) in the radial direction of the rotor disk (18). The gas turbine disassembling/assembling method comprises a seal plate restriction state switching step for switching between, by operating the seal plate movement restriction part (46) from the other side in the axial direction, a seal plate unrestricted state where the seal plate movement restriction part (46) does not restrict radial movement of the seal plate (44) and a seal plate restricted state where at least a portion of the seal plate movement restriction part (46) projects from the seal plate (44) toward the other side in the axial direction and restricts the radial movement of the seal plate (44).
