Abstract
An addendum shape portion of a panel material is drawn by a drawing portion of a press forming die by an amount equal to or less than the limit to which the panel material can be drawn, whereby a to-be-product portion of the panel material is roughly conformed to a forming face of a punch. In this state, the to-be-product portion of the panel material is stretched or drawn. Accordingly, the cross section of the to-be-product portion is uniformly changed at the minimum level, which makes it possible to produce, by press forming, a fender panel made of aluminum base alloy, which has a great plane dimension L and high quality. As a result, flexibility in the design of panel parts, which are formed by pressing the panel material into shapes, is increased.
