Zusammenfassung:	PURPOSE:To certainly fix a clamping tool for clamping a screw member at a working point to carry out clamping work. CONSTITUTION:A stopper bolt 11 to prevent rattling of a fork 5 by way of making contact with a back surface part 4a of a fork bar 4 is screwed in a lower hook 7 to hook the fork 5. The stopper bolt 11 is locked by a lock nut 17. A clamping handle bar 18 to operate the lock nut 17, etc., is inserted into the stopper bolt 11. A fixed plate 19 is inserted into a grip part of the clamping handle bar 18. At this time, an engagement recessed part is formed on a head part 12 of the stopper bolt 11 and an engagement protruded part 31 is formed on the fixed plate 19, and the clamping handle bar 18 is fixed on the stopper bolt 11 as the engagement recessed part and the engagement protruded part 21 are engaged with each other. A worker releases engagement of the engagement recessed part and the engagement protruded part 31 and carries out clamping work of the lock nut 17, etc., with the clamping handle bar 18.
