Abstract
A ventilation flow path for guiding a compressed gas flowing between two blade rows adjacent in an axial direction to an interior of a compressor rotor shaft is formed in the compressor rotor shaft. The ventilation flow path has an introduction part, a plurality of branch parts, and a collection part. The introduction part guides the compressed gas flowing between the two blade rows into the compressor rotor shaft. The plurality of branch parts branch out from the introduction part, and are formed in mutually different positions in the axial direction. The collection part is connected to each of the plurality of branch parts. The compressed gas flows into the collection part after passing through the plurality of branch parts, and then, the compressed gas that has flowed in flows outside through the collection part.
