Abstract
A steam turbine provided with: a rotor; a plurality of movable blades each of which has a movable blade body and a shroud, and which are circumferentially arranged at intervals; a casing that has a recessed section for accommodating the shroud; fins that form clearances from the outer circumferential surface of the shroud; a stator blade support part disposed on the downstream side of the recessed section; a plurality of stator blades circumferentially arranged at intervals; and an annular partition plate that extends from a recessed section downstream surface toward the upstream side thereof. The casing has formed therein a bypass flow passage that communicates a region radially outside of the partition plate and a region between the stator blades.
