Next, the replacing sheet 8 is further pushed in until it goes over the stop projection 11 provided to a base part 5 and the stop projection 13 provided along the outer periphery of the breathing hole 7. The replacing sheet 8 is stopped by the stop projections 11 and 13 to be fixed on the surface of the flange part 3.
