PURPOSE: A wire feeding device is provided to increase rotational force by rotating each slave gear with two output shafts of a decelerator, to stably feed a wire by accurately transmitting rotational force to the salve gears and to reduce the cost of the decelerator with the reduced number of components. CONSTITUTION: A decelerator is combined with a drive motor through a rotating shaft and a wire feeding device rotates plural wire feeding rollers and pressurizing rollers with power from the decelerator through third planetary gears, driving gears and slave gears. The wire feeding device comprises a sun gear in a rotating shaft of a driving motor in a decelerator case; a first planetary gear engaged with the sun gear with larger diameter than that of the sun gear; a second planetary gear on the first planetary gear with smaller diameter than that of the first planetary gear; and shafts supporting third planetary gears engaged with the first planetary gears between disc frame and the decelerator case. Wire feeding rollers and the driving gears are placed in each shaft end of the third planetary gears.
