るプレス成形装置、 In a press forming machine that presses and holds a blank material between a die with a die hole and a blank holder, the die and a punch work together to draw the blank material into the die hole side and draw it into a predetermined shape. An insert die is installed on the blank pressing surface of one of the members, which is horizontally slidable and which cooperates with the other member to perform flange bending on the end of the blank when the blank is pressed and held. and an elastic means is provided between the one member and the insert die to apply a force to the insert die to counteract the drawing force of the blank toward the die hole side. ,
