Abstract

PURPOSE: To prevent a moving blade from an untwist phenomenon and improve a performance of turbine by a method wherein protruded and recessed portions are provided on an abutting surface between connecting portions of eaves for the moving blade and a cover therefor to engage each of them.
CONSTITUTION: A moving blade cover 15 is abutted against connecting portions 3, 3' of eaves for the moving blade 2. Pins 16, 16' of the moving blade cover 15 are coupled with penetrating holes 14, 14' of the eaves 3, 3'. Guide surfaces 17, 17' and recessed portions 18, 18' are formed on the moving blade cover 15 to engage with the eaves 3, 3' of the moving blade. According to this engagement, an untwist phenomenon of each moving blade may be prevented. Further, a stopper 19 is protrudingly provided on the moving blade cover 15 to constitute so that side end portions of each eaves 3, 3' can be abutted against the stopper, therefore, the untwisted phenomenon of the moving blade 2 may be prevented also by the stopper 19.
