    • PROBLEM TO BE SOLVED: To extend interval of periodic maintenance work by reducing wear of blades.
      SOLUTION: This invention relates to a variable-setting stator blade housed in a turbo machine casing and provided with an airfoil 12, a plate and a pivot 14. The variable-setting stator blade is provided with a platform including a disk. The disk is fitted in the plate on one face and presses against a wall on another face. The fitted platform is prevented from rotating around a pivot shaft. The variable-setting stator blade is provided with at least one rotation prevention tab 22 fixed and attached on a disk interacting with a butting surface formed on the plate. This invention reduces wear of a blade plate and enables to prevent loss of function of a system caused by a result of the same. This invention provides a method for repairing the worn blade.
