Abstract
Shock absorbers () are attached to a press apparatus (). The press apparatus () has a lower die unit () and an upper die unit () that is movable in vertical directions; the lower die unit and the upper die unit are capable of cooperating with each other to perform press-forming on a blank (W). The upper die unit () has an upper forming die () that serves as a forming die to perform press-forming on the blank (W) and upper blank holders () that partially serve as blank holders. The shock absorbers () are respectively disposed between the upper forming die () and the upper blank holders (), and when the upper die unit () is moved upward away from the lower die unit () to open the upper and lower forming dies after press-forming is performed on the blank (W), impact applied to the upper blank holders () by the upper forming die () are respectively absorbed by the shock absorbers ().
