Zusammenfassung:PURPOSE:To reliably prevent the draw back of a positioning pin during insertion of the positioning in a pin hole by providing a collet chuck to nip a push rod and the positioning pin and prevent the draw back of the positioning pin during release of the push rod from the positioning pin. CONSTITUTION:When a positioning pin is inserted in a pin hole D, the positioning pin is pushed in the pin hole D by means of a push rod 67. With this state, the part, protruded from the pin hole D, of the positioning pin is then nipped by means of a collet chuck 46. Then, after a push rod 46 is escaped upward, the collet chuck 46 is released from a lock and finally, the collet chuck is escaped upward. The above operation is effected only through expansion and contraction of a single elevating cylinder 8, an equipment cost is reduced, and reliability is also improved.
