入口側の翼構造。 A turbine inlet side consisting of a stator vane fixed to a casing, and a rotor blade that is implanted in the rotor opposite to the stator vane, has a shroud at its tip, and rotates the rotor with working fluid sent through the stator vane. In the blade structure, a shelf portion located on the circumferentially outer side of the rotor blade is formed on the stator blade, and an extremely small gap is formed between the stator blade and the shroud at a position facing the shroud. The shroud is characterized in that an axial seal portion is formed, and cut surfaces are provided on the circumferentially outer side of the axial seal portion and on the circumferentially inner side of the shroud that faces the axial seal portion and are substantially parallel to each other at different levels. The blade structure on the turbine inlet side.
