Claims

[Scope of utility model registration request]

A blade stopping device for circumferential positioning when a single blade having a T-shaped blade root is inserted and planted in the circumferential direction into a blade groove formed along the circumferential direction of the rotor. Positioning holes are formed in the bottom of the blade groove at predetermined intervals in the circumferential direction, and a locking member that can be inserted into and locked in the hole is attached to the bottom of a specific single blade, and the circumference of this locking member is A wing stop device characterized in that the width in the direction is set to match the root end surfaces of the individual blades disposed on both sides of the specific individual blade.
