Embodiment 3 INDUSTRIAL APPLICABILITY [0084] Aradial?oWsteamturbineaccordingtothepresent invention can be used as a steam turbine used for various industrial facilities because the turbine unit including the rotor disk and the stator disk can be added according to the steam supply condition at the spot. For example, it can be applicable to a steam turbine for ships utiliZing the Wasted [0076] Embodiment3describestheexampleoftheradial heatfromtheengine,anditcanbeapplicabletoasteam ?oW steam turbine in Which the steam ?oW opening 41 is formed in a single side of the casing 40, and the steam is supplied from the steam supply source (itisnot shoWn in ?gures)tothissinglesidedirection.

[0078] Inthepriorart,mostconventionalradial?oW steam turbinesinWhichtherotorbladesaremountedontothesingle sideoftherotordisksupplythesteamfromasingledirection to the single side surface of the rotor disk. Therefore, the thrust force along to the rotation shaft acts on the rotor disk from a single direction. For example, in order to reduce the axis direction thrust force impressed to the rotor disk, the prior art 5 employs a small hole formed on the rotor disk. HoWever, the steam passing through this small hole is not utiliZed. It is regarded as the loss of the leaked steam. [0079] Ontheotherhand,theradial?oWsteamturbineof the present invention comprises the rotor blades 21 arrayed both side of the rotor disk 20, the through opening 22 in the vicinity of the rotor disk 20 for securing the steam supply route in the axis direction.
