<p>PROBLEM TO BE SOLVED: To eliminate the need for the work of preventing slip-off of a bolt by a nut through a method generally carried out to perform cantilever holding of a piping band by a turn buckle and to facilitate a piping work. SOLUTION: Bolt slip-off preventing lock edges 6 each having a thinned tip, positioned ahead of the screw groove of a bolt 15, is formed at the edge parts of a bolt holes 5, formed in a pair of the cantilever support pieces 4 positioned facing each other of a turn buckle 1, by a squeezing work through the working of a press. By hooking and locking a bolt 15 inserting through both the suspension support piece 4 of the turn buckle 1 and one fastening piece 12 of a piping band 7, cantilever holding of the piping band 7 through the bolt 15 is practicable without using a nut 16.</p> |
