PROBLEM TO BE SOLVED: To provide a soldering device, in which a rotary part is not exposed constantly to air in a melting solder liquid level, maintenance work can be executed easily, and which is not affected by stray currents. SOLUTION: A motor 6 is arranged on the tank base 2 of a tank 1, and a pipe 5 is installed by connecting it to the surface of melting solder liquid level from the tank base 2 of the tank 1. Rotation of the motor 6 is transmitted into the pump 5 and a pump 12 in melting solder 10 by a hollow pump shaft 8 through a rotary driving shaft 7 from the upper end of the rotary driving shaft 7. The hollow pump shaft 8 is covered by a sealing cap 4 and is detached. Melting solder 10 is supplied, and the shaft is filled with it so as to shield it from air.
