Abstract

PURPOSE: To prevent a generation of crack in the peripheral part of a tenon, by reducing a weight in the central portion of a pitch between turbine moving blades.
CONSTITUTION: A thin pad portion 15 is formed in the central part of a pitch 4 between turbine moving blades 1 to decrease a weight in said portion. In this way, a centrifugal force generated in the weight decreased portion is reduced to cause a reduction of the bending stress generated in a tenon peripheral part 3a and further equalize the bending stress in the pitch 4 between the moving blades. Accordingly, the generation of a crack in the tenon peripheral part 3a can be prevented.
