PROBLEM TO BE SOLVED: To provide a gas nozzle for controlling deposition of hot dip galvanizing. SOLUTION: In the gas nozzle for controlling deposition of hot dip galvanizing, a first gate is provided on the side opposite to a gas feed port provided on an upper part of the gas nozzle, and a second gate is provided parallel to the first gate on an upper gas feed side on a slit nozzle side. Gas fed from the gas feed port collides with a lower portion of a first chamber inside the gas nozzle, is passed through a space between the first and second gates, rectified thereby, further unified in a second chamber, and ejected from the slit nozzle.
