To provide a reliable turbine moving blade keeping connection condition of an integral cover of adjoining blades by preventing rotation of blade root part even if it is short blade and not having high stress apply on an engagement part of the blade root part and a disk groove.
The turbine moving blade touching and restricting the adjoining integral cover 7 by elastic recovery force of a blade profile part 2 tending to deform torsionally by pushing a turbine disk 5 from a turbine rotary shaft direction side is provided with a groove 8 passing below a disk groove 6 and provided along a blade rotation direction, a circumference surface 41 provided on a tip side end surface of the blade root part 4 pushed in the disk groove 6, and a pressing member 9 built in the groove 8 to make a radial direction outer circumference surface abut on a circumference surface 41 of the blade root part 4.
