Summary:PROBLEM TO BE SOLVED: To sufficiently cover gaps between a rotor wheel and rotor blades and thereby inhibit inflow of a working fluid and outflow of a cooling medium.SOLUTION: A sealing structure 39 is used to cover gaps between a rotor wheel 33 and rotor blades 34. The sealing structure includes holding parts 331 and non-annular cover plates 352. The holding parts are provided at the rotor blades. Each non-annular cover plate is held so as to span between the adjacent holding parts. 【課題】ロータホイールと動翼との間の隙間を十分に覆うことによって作動流体の流入や冷却媒体の流出を抑制する。【解決手段】封止構造体３９は、ロータホイール３３と動翼３４との間の隙間を覆うための封止構造体に関する。封止構造体は、保持部３３１と非環状カバープレート３５２とを有する。保持部は、動翼に設けられる。非環状カバープレートは、隣り合う保持部間に跨るようにして保持される。【選択図】図７
