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. |
