摘要： To prevent evaporated flux from being attached to rotation axes of motors which rotate fans positioned in a preheating zone, a main heating zone and a cooling zone and being solidified, the evaporated flux is efficiently and surely collected with the flux liquefying before the flux is solidified and having fluidity. A drain portion 20 constituting a flux collection apparatus 10A is formed at a side of a motor base 16 opposed to the fan and at a circumferential portion of the rotation axis 14. A surface of the drain portion 20 opposed to the fan is formed as an inclined surface 20A which is inclined from a level position of the motor base 16 to a discharge port 46 provided at a back side of the motor base 16. The flux collected to a center portion of the motor base 16 by the rotation drive of the fan is flown to the drain portion 20 formed in the center portion of the motor base 16, is flown along the inclined surface 20A and contained into a collection container 34 from the drain portion 20 through the discharge port 46, a drain pipe and a pipe 48.
