PROBLEM TO BE SOLVED: To provide a pressing method of a plate material, in which the number of times of pressing is reduced.SOLUTION: In the pressing method of a plate material, a circular-arc shape is formed by pressing a plate material at a plurality of press positions while moving the positions in the circular-arc direction when pressing the plate material into the circular-arc shape by pushing a driven die into a fixed die. A pushing-in amount at a second press position that is adjacent to a first press position is decided based on the bending angle with respect to the pushing-in amount at the first press position. |
