PROBLEM TO BE SOLVED: To provide a turbine moving blade fixing structure supporting axial force applied backward to a moving blade to transmit the axial force to a disk and improving engine performance by considerably reducing leakage flow from a clearance because there is hardly a clearance between the blade rear skirt and a disk post. SOLUTION: The disk 3 has a stopper 10 extending outward from the downstream end of the disk post 3b and having an upstream end face 10 formed almost as a plane. The blade rear skirt 12c of the turbine moving blade 1a has a downstream end 13 formed to come in close contact with the upstream end face 10a of the stopper. The downstream end 13 of the blade rear skirt 12c is supported by the stopper 10 at the downstream end of the disk post to perform axial positioning, and the axial force applied backward to the moving blade 1a is supported by the stopper and transmitted to the disk.
