PURPOSE:To simultaneously and surely press fit a bearing bush to a bearing hole by positioning a casing workpiece clamped in a condition that a through hole, formed in a supporting fixture, is positioned coaxially with the bearing hole, in the case that the supporting fixture for supporting press fit thrust is brought into contact with an internal wall of the casing workpiece, in order to press fit the bearing bush to the die-cast molded casing workpiece having at least a pair of thin thickness partitions provided with the bearing hole coaxially with a lateral axis. CONSTITUTION:A workpiece 10 is positioned to be clamped by pins 24, 26 provided in a predetermined relation in a base 20 and a clamp device. Simultaneously in a constitution, in the case that a pair of clamping pawls 50a, 50b formed with a through hole are positioned to come into contact with an internal wall of opposed thin thickness partitions through opening action by rotating an oil hydraulic motor 32, the through hole of the clamping pawl is positioned coaxially with a bearing hole. |
