Beschreibung
Zusammenfassung:	A steam turbine (1) includes a rotor shaft (21) which includes a disk portion (23) fixed to a shaft core portion (22) rotating about an axis (Ar), a plurality of rotor blade rows (31) which are fixed to an outer periphery of the disk portion (23), and a stator vane row (41) which is adjacent to an upstream side of the rotor blade row (31). A gap flow passage (100A), which extends from a steam main flow passage (15) toward a radially inner side, is formed in a gap between the rotor blade row (31) and the stator vane row (41) configuring a speed governing stage (50a). A communication passage (102), which includes first end which communicates with the gap flow passage (100A) and the outer end which communicates with a space in which steam having a higher pressure than a pressure of steam inside the gap flow passage (100A) exists, is formed in the disk portion (23).
