Beschreibung
Zusammenfassung:	A method for manufacturing a gas wiping nozzle provided with a pair of lip parts facing each other and a slit formed as a gas ejection port between the pair of lip parts and blowing gas from the slit against a steel strip pulled up from a plating bath to adjust a thickness of a molten metal film deposited on a surface of the steel strip, which method includes fitting fitting projections provided at one lip part with fitting holes provided at another slip part and fastening the pair of lip parts together in the fitted state, the fitting projections fitted with the fitting holes, two pairs of the fitting projections and the fitting holes provided separated by a distance in a width direction of the steel strip, relative movement between the pair of lip parts in a thickness direction of the steel strip restricted in the fitted state.
