PROBLEM TO BE SOLVED: To improve an assembling condition of an LP turbine for reducing risk of damaging an intershaft bearing. SOLUTION: A second shaft is assembled by a bearing, and this bearing has an outside ring shrinkage-fitted inside a journal integrated into a first module, and an inside ring integrated into a second shaft. A second module is assembled on the first module by engagement with the inside ring of the second shaft in the journal having the outside ring, and includes a step of fitting the second module to the second shaft up to a predetermined distance from the journal, a step of aligning and controlling the second shaft with respect to the journal on the basis of the fact of measuring a distance deviation with respect to a reference on the journal, a step of heating and expanding an outside surface of the journal, and a step of completing mutual fitting of the second shaft.
