<p>PROBLEM TO BE SOLVED: To improve working efficiency at one-handedly fastening a bolt and a nut by performing combination of the leg parts of a turnbuckle with the end part of one hanging band by the use of a nut having a guide hole for the internal thread. SOLUTION: The upper end of one hanging band 5A and both leg parts 3A, 3B of a turnbuckle 3 are connected together with a nut 7, and the nut 7 is fixed by a method such as hard caulking so as not to co-rotate accompanying rotation of a bolt 6. The bolt 6 is rotationally movably fixed to the end part of the other hanging band 5B by a bolt fixing means 6A, and even when the bolt 6 is detached from the nut 7, the respective ones are prevented from falling. Further, a guide hole 7C is provided on the first portion of the internal thread of the nut 7, and the inner diameter is gradually reduced toward the internal thread. Hereby, even if the bolt 6 is inserted in the oblique direction as shown by the arrow mark (b), the bolt 6 is easily corrected into the state of the arrow mark (a) by means of the guide hole 7C.</p> |
