A gear pivotally attached to the movable holding member 42 and fixed to the proximal end of the pointer 47 is meshed with a rack fixed to the guide member 40.

In FIG. 15, the wrapping wire 8 let out from the wire bobbin 9 passes through the floating sheave 41 and is wrapped around the suspension bridge cable 5. In this case, when the tension of the wrapping wire 8 becomes larger than a predetermined value, The floating sheave 41 and the movable holding member 42 are connected to the tension spring 43
is moved in the direction of arrow B against the elasticity of
The operating member 44 is also moved in the direction of arrow B via the lever operating spring 45, and the lever 39 is rotated in the loosening direction to loosen the brake band 33, so that the tension on the wrapping wire 8 decreases. .
Further, when the tension of the wrapping wire 8 becomes smaller than a predetermined value, the floating sheave 41 and the movable holding member 42 are moved in the direction of arrow C by the elasticity of the tensioning spring 43, so that the lever 39 is rotated in the tightening direction. As the brake band 33 is tightened, the tension of the wrapping wire 8 increases, and in this way, the tension of the wrapping wire 8 is automatically adjusted to a predetermined value.

Note that the tape bobbin 7 can also be attached with a tension adjustment mechanism having the structure shown in FIG. 15.

Since the wire bobbin 9 on which the wrapping wire 8 is wound is rotatably attached, each of the rotating frames 2 and 3 is rotated by the drive device while the traveling frame 1 is guided by the suspension bridge cable 5 and travels. By doing so, it is possible to wrap the waterproof and rustproof tape 6 around the suspension bridge cable 5 and to wrap the wrapping wire 8 on top of the wrapped tape, so that the liquid waterproof and rustproof paste can be manually wrapped. There is no fear of the paste falling, which is a disadvantage when applying it to suspension bridge cables, and the waterproof and rust-proof layer can be uniformly provided on the surface of the suspension bridge cable 5. Furthermore, the formation of the waterproof and rust-proof layer and the wrapping wire 8 are easy. Wrapping of the wrapping wire can be carried out continuously and simultaneously simultaneously and with high efficiency by mechanical force, and furthermore, the propulsion cable is provided with a stepped portion 10 that engages with the wrapping end of the wrapping wire wound around the suspension bridge cable 5.
