Zusammenfassung:	PURPOSE:To eliminate the installation of camber preventive jigs for each of wiring boards and to improve productivity by using a roller group which contacts with the rear surface of the wiring board and a roller shaft supporting plate to constitute the camber preventive jigs which are so fixed as to straddle the solder ejection port of an automatic soldering device. CONSTITUTION:The printed wiring board A is passed in a specified direction in a solder tank 8 provided with the solder ejection port 7a contg. melted solder, by which the wiring board is soldered. Even if the board A is to camber downward from both ends a2 to the central part, the camber preventive jigs 11 receive the rear surface a1 of the board A from below and prevent the camber thereof. Since the camber preventive roller 12 group is nearly similar hardness to the board or soft and therefore the board A is not scratched. When the roller 12 group wears, the roller 12 group is replaced with the new roller group by loosening the nuts of adjusting bolts 22 and moving the supporting plate 23.
