Claims

[Scope of utility model registration request]

10-Provide a notch that opens on both sides of the rota disc at a position facing downward from the groove of the rotor disc.11. On the other hand, the implanted part of the blade has a tapered surface that is inclined at a constant angle toward both edges of the bottom of the implanted part, and these blades and the rotor disk are connected to each other. A pair of connecting pieces are fitted into the grooves of the rotor discs to be integrated, and the i-ends of the blades are brought into contact with the tapered surfaces of the blades in each of the notches, thereby moving the entire blade in the radial direction of the rotor disks. A turbine blade fixing device characterized in that a fastening member is removed and fitted.
