摘要：
A steam turbine has a stationary section, a turbine rotor, nozzle diaphragms, a steam passage section, a nozzle box and a sealing. The stationary section includes a casing. The turbine rotor includes moving blade stages. Each of the moving blade stages has turbine moving blades. Each of the nozzle diaphragms has turbine nozzles. The moving blade portions and the turbine nozzle portions constitute the steam passage. The nozzle box is held by the stationary section and arranged at an upstream side of the steam passage coaxially with the turbine rotor. The sealing divides a space between the turbine rotor and the casing into a first space provided at an inner side and a second space provided at an outer side of the nozzle box.
