PROBLEM TO BE SOLVED: To provide a repair method for a gas turbine moving blade facilitating repair of a damaged part such as a crack, in the gas turbine moving blade. SOLUTION: The gas turbine moving blade is constituted of a blade part 4 and a fir three part 5 fitted into an embedment groove worked in an outer periphery of a turbine wheel. The gas turbine moving blade has a shroud cover 7 with an uneven part 8 formed at an outer periphery thereof, the uneven parts 8 are mutually fitted to neighboring moving blades, so that the gas turbine moving blades are engaged. Since a part near the crack 9 generated in the recesses part 6 of the uneven part 8 of the shroud cover 7 is removed in a circular arc shape (circular shape) from above, along a height direction of the gas turbine moving blade, the repair is facilitated.
