Abstract
A forging die device is provided with an upper dieand a lower die. At least one die() of the upper dieand the lower diehas a die holder() which surrounds the outer periphery of the die() and holds the die(). The die holder() is configured to bear the radial tensile stress (tensile force) received by the die() during forging. By this means, the die() can be miniaturized.
