Abstract

This press forming method is for press forming a T-shaped part 1 having a top portion 3 connected via a connecting portion 13 for a vertical top portion 9 and a horizontal top portion 11, a wall portion 5 formed from the vertical top portion 9 of the top portion 3 to the horizontal top portion 11 via the connecting portion 13, and a flange part 7 formed continuously at the lower edge of the wall portion 5, said press forming method being characterized by: comprising a first forming step for drawing to an intermediate shaped part 21 having a protruding shaped portion 15 formed on the connecting portion 13, a trimming step for obtaining a trimmed part 41 by trimming the intermediate shaped part 21, and a second forming step for forming the T-shaped part 1 in a target shape by form shaping the trimmed part 41; and, in the second forming step, flattening the protruding shaped portion 15 and allowing material to flow into the wall portion 5a continuous from the connecting portion 13.
