クを起こし、導体が切断する等の欠点があった。Conventionally, a wheel car is hung on an arm of a telephone pole, a rope is connected to a cable loaded on the cable car through the cable, and construction is performed. When pulling out and extending a cable while taking up a rope with a winch mounted on a car, the cable car side may be used, for example, as described in Utility Model Registration No. 307914. However, there was no problem because the cable was extended while the cable was braked so that the cable had a predetermined sag. However, after the construction was completed, the cable was replaced with a cable car. When the cable is wound around the cable reel, the cable is not subjected to forcible back tension. Therefore, as the cable length is shortened and the weight of the cable is reduced, the back tension due to the weight of the cable is reduced. Weakens and corrects cable curl In order to Rukoto can not, there is a drawback that can not be neatly wound. Also, if the reel is unwound, the cables in the adjacent left and right upper and lower layers become entangled with each other when the cable is next fed, and the cables are rubbed with each other, causing scratches on the sheet. Or, there are disadvantages such as kinking and disconnection of the conductor.

If the positional relationship between the construction vehicle and the gold wheel is not properly adjusted, there is a disadvantage that the rope cannot be neatly aligned and wound on the reel.
The present invention has been made to solve the above-mentioned disadvantages,
When winding the cable around the cable car after the work is completed, the back tension is applied on the construction car side.
The present invention provides a torque roller capable of acting as a key device and further acting as a guide roll for aligning and winding a rope on a reel attached to a winch shaft when a cable is extended. It is the purpose.
