PROBLEM TO BE SOLVED: To solve the problem that a conventional apparatus for preventing a printed wiring board warpage is not capable of preventing the warpage during the time from just before going out of an automatic soldering apparatus until going to the next process apparatus. SOLUTION: The apparatus includes a part to be inserted in an automatic soldering apparatus, a mechanism of straightly arranged non-driving thin rollers, a mechanism for adjusting the roller height, a mechanism for adjusting the height positions of both end rollers of the roller line, and an opening at a roller holder. This prevents the warpage of the printed wiring board during the time from just before going out of an automatic soldering apparatus until going to the next process apparatus.
