Abstract
A steam turbineaccording to an embodiment includes: rotor blade cascades each made up at a turbine rotor; an inner casingwhere the turbine rotoris provided to penetrate; an outer casingsurrounding the inner casing; stationary blade cascades each made up at an inner side of the inner casing; and an annular diffuserprovided at a downstream side of a final turbine stage, formed by a steam guideand a bearing cone, and discharging steam toward outside in a radial direction. An enlarged inclination angle θ1 of an inner surfaceof a diaphragm outer ringat the final turbine stage relative to a turbine rotor axial direction is an enlarged inclination angle θ2 of an inner surfaceat an inlet of the steam guiderelative to the turbine rotor axial direction or more.
