動翼のサポート構造。 In a structure in which the blade group heads of multiple turbine rotor blades are integrally supported by a shroud, the tenon flange protrudes from the upper end side of the head of the rotor blade tenon, and the head side of the rotor blade continues to the bottom of the tenon. In order to engage with the socket groove drilled in the shroud, tenon holes and socket parts corresponding to each position and shape are formed on the side of the shroud that comes into contact with the tenon and rotor blade of each of the divided shrouds. A support structure for a turbine rotor blade, characterized in that the circumferential butt portions of the blades are welded.
