PROBLEM TO BE SOLVED: To provide a platform 3 of a gas turbine moving blade capable of suppressing influence of thermal elongation and improving cooling performance. SOLUTION: A structure of the gas turbine moving blade is composed of a peripheral fringe of the platform 3 of the gas turbine moving blade, a bottom face of the platform 3, and a shank of the moving blade. A cavity 17 is blocked by arranging a sealing plate 18 to seal a recessed part. On the other hand, a supply passage is formed to supply air from cooling passages to the cavity 17 through the inside of the shank, and each of the cooling passages is for cooling the inside of gas turbine moving blade by air blown out onto a surface of the platform 3 from the cavity 17. A method for mounting the sealing plate 18 properly is also provided. COPYRIGHT: (C)2007,JPO&INPIT
