Abstract
A steam turbine (ST) includes a rotor (11) which is rotatable around an axis (Ar), an inner casing (21) surrounding the rotor (11) from an outer peripheral side, an outer casing (30) surrounding the rotor (11) and the inner casing (21) and defining an exhaust chamber between the inner casing (21) and the outer casing (30), the steam being exhausted to the exhaust chamber (30s), and a flow guide (27) which has a tubular shape and is installed on one end portion of the inner casing 21 in an axial direction (Da) in the exhaust chamber (30s) to guide the steam discharged from the rotor (11). The flow guide (27) has a turning surface (RA) which is connected to an outer peripheral surface (27A) and turns a fluid flowing along the outer peripheral surface (27A) toward the other side in the axial direction (Da).
