Abstract: A hold device is attached to press tooling. The hold device includes a distance member attached to a holder, and a moving device attached to a first die unit. The holder is provided in a movable manner with respect to a punch in a press direction, and a pad is provided in a movable manner with respect to a die in the press direction. The distance member is pivotable between a home position in which the distance member does not come into contact with the second die and a preventive position in which the distance between the pad and the holder in the press direction is prevented from being equal to or less than a predetermined distance. As the holder moves relative to the punch in the first direction, the moving device causes the distance member to pivot from the home position toward the preventive position.
