Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a removing device of foreign matter on bath surface in a snout installed in a plating bath. SOLUTION: On the plating bath surface in the snout, one end part of a U-type pipe-like foreign matter introducing cylinder having a suction inlet for sucking dross on the bath surface by protruding a part of the cutting hole from the bath surface, is arranged, and a jet pump acted with inert gas of N2 gas, etc., is arranged on the midway of the other end side of the introducing cylinder for exhausting the bath metal containing the dross from an exhaust port formed at the other end side wall of the introducing cylinder. The interval of exchange of an immersion member in the plating bath is extended, and a high quality plated steel sheet free from flaw and also, containing no foreign matter, can be produced.
