PURPOSE:To increase the mounting strength of a turbine blade by installing the both end tabs to be formed on the turbine blade, at the innermost end part and the approximately outermost part of the turbine blade. CONSTITUTION:A plurality of slits 13 are formed on the shell part to a turbine shell 11 and the most internal one of the slits 13 is cut in the L-shaped form on the corner part which is a boundary between the shell part and the flange part of said shell 11. On the other hand in addition to a tab 14 which is inserted in other of the slits 13, another tab 14 is so formed on the most internal end part of the shell 11 that the tab 14 can be inserted in the most internal slit 13. After the turbine blade 12 is inserted in the slits on the turbine shell 11, the projectingly exposed parts of the tabs 14 are caulked to be fixed firmly.
