Abstract

A structure for retaining a turbine rotor blade is configured so that the axial deformation of a locking piece at an end thereof is prevented the locking piece being exposed through an insertion window and so that the occurrence of a crack in a weld section is prevented. One end of at least one of adjacent locking pieces (12 66) exposed through an insertion window (68) is provided with a thick wall section (13) protruding in the plate thickness direction so as to enter the inside of the window section (68).
