PROBLEM TO BE SOLVED: To provide a draining apparatus with which a large quantity of liquid coolant flowing into the lower part along a steel strip can be drained. SOLUTION: One pair of an upper-step nozzle 35 and a lower-step nozzle 35 facedly disposed so as to interpose the steel strip S, are arranged at the outlet sides of a first cooling zone 1 and a second cooling zone 2 for cooling the steel strip S conveyed to the vertical direction and heated by using air and water, and to facing surface with the steel strip S in the upper-step nozzle 35 and the lower-step nozzle 36, an opening hole is arranged so as to cross at the right angle to the conveying direction of the steel strip S, and upper slits 35b,36b and lower slits 35c,36c for draining the cooling water W flowing downward along the steel strip S by injecting the air A, are made to form along the conveying direction of the steel strip S.
