    Abstract: PROBLEM TO BE SOLVED: To reuse a shield to be used in the case of coating a tip of a blade, and to improve the durability of the shield. SOLUTION: A shield assembly 12 for masking an aerofoil 24 includes a shield 40 arranged in the periphery of the air foil 24 and a locking member 42 for preventing the movement of the shield 40 from the set position. The shield 40 includes two chord directional surfaces 52, 62 connected to each other at a front end 48, and these surfaces are extended from the front end 48 to rear ends 54, 64, and connected to each other at rear ends 54, 64 by a pair of tabs 56, 58. The locking member 52 is extended inside of a cooling air hole 36 of the air foil 24 so as to prevent the movement of the shield 40, and engaged with the shield 40 or formed as a part of the shield 40.

    Abstract: PROBLEM TO BE SOLVED: To prevent the movement of a shield to be used when coating a tip of a blade. SOLUTION: A stopper member 42 is extended between a flow leading assembly and a shield for this flow leading assembly. This stopper member 42 includes a pair of L-shaped projecting parts 112, 116, and these projecting parts 112, 116 are engaged with a corresponding pair of cooling air holes of the flow leading assembly. The stopper member 42 also includes a pair of tabs 114, 118 so that the stopper member 42 can be engaged with an opening part of the shield. The stopper member 42 also has an intermediate area 122 extended in the blade cross section. With this structure of the stopper member 42, movement of the shield in relation to the flow leading assembly in the set condition is prevented.

    Abstract: PROBLEM TO BE SOLVED: To reuse a shield to be used in the case of coating a tip of a blade. SOLUTION: A shield 40 for masking an aerofoil 24 includes two chord directional surfaces 52, 62 connected to each other at a front end 48, and each surface is extended from the front end 48 to rear ends 54, 64, and connected to each other at rear ends 54, 64 by a pair of tabs 56, 58. These tabs 56, 58 are extended while passing through from an opening of one surface to an opening of the other surface, and folded so as to tightly get into contact with the other surface. The tabs 56, 58 are pushed so as to tightly get into contact with the other surface in the set condition, and the other surface is thereby pushed to the aerofoil 24.
