Claims

[Scope of utility model registration request]

Seal plates that cover the blade grooves of the turbine rotor and stop the blades from moving in the axial direction are provided on a circular ring member that covers the base of the rotor and on the radial end of this circular ring member, one for each blade. A blade stop device for a turbine, characterized in that by dividing a Christmas tree-shaped part into a stop member that holds down the part, each part is formed into a shape that is advantageous in terms of centrifugal strength without restricting the space between adjacent stator blade shrouds.
