Abstract
A fixed-side connecting portionis provided on an end of the fixed barwhile a movable-side connecting portionis provided on an end of the movable bar. An air clampis housed within the fixed bar. By pneumatically driving the air clampwhile the movable-side connecting portionis superimposed on an upper side of the fixed-side connecting portion, a clamp memberprotrudes from a caseto be downwardly rotated and holds the movable-side connecting portionagainst the fixed-side connecting portion. Since the clamp memberis pneumatically driven, a die replacement time can be shortened. In addition, since the air clampis housed within the fixed bar, the size of a transfer feedercan be reduced.
