PROBLEM TO BE SOLVED: To provide a pole-top safety belt attaching tool which is not opened even if something wrong happens to a tightening means such as a bolt, a butterfly nut, etc., and by which a pole-top safety belt can be attached easily.
SOLUTION: A pole-top safety belt is attached to a cable 49 having a messenger wire 40 by a pole-top safety belt attaching tool. In the pole-top safety belt attaching tool, the upper parts of a pair of attaching members 2 and 3 whose top parts are linked with each other with a hinge are formed into round surrounding parts 7 and 7 which surround the cable 39 and the lower parts of the pair of the attaching members 2 and 3 are extended downward vertically to form folded plates 10 and 11. Wire holding parts 8 and 9 which hold the messenger wire 4 by opening and closing the attaching members 2 and 3 are formed in the upper part of the inner circumference of the surrounding parts 7 and 7 and retaining holes 12 and 13 with which the retaining metal fitting of a safety belt is retained are formed in the respective folded plates 10 and 11. Above the retaining holes 12 and 13, a fixing screw is made to protrude from the upper part of one 11 of the folded plates 10 and 11 toward the other folded plate 10 in which a through-hole 16 through which the the fixing screw is inserted when the attaching members 2 and 3 are closed is formed and the fixing screw is mated with a nut member 6 by which the folded plates 2 and 3 are tightened.
