PROBLEM TO BE SOLVED: To provide a method for fixing a refrigerant pipe in an auger type ice making machine in which a brazing work having a superior working efficiency can be carried out and a heat exchanging efficiency enabling ice of superior stable quality to be manufactured is improved. SOLUTION: Each of both released ends 2-1, 2-2 of a refrigerant pipe 2 wound around an opening 1-1 of an ice-making cylinder 1 and an outer circumference of the ice-making cylinder 1 in a close helical manner is closely closed and protected by a covering member comprised of a metallic cap 4 of superior heat-resistance characteristic and either a tube or a tape 3. Then, the pipe is fully immersed in a soldering tank A set and monitored at a melted metal temperature higher than a melting point of solder 5, thereby brazing the refrigerant pipe 2 against the ice making cylinder 1 and fixed to it.
