The present invention relates to a wire tension controlling apparatus, and includes: a supporting body that has a bar shape; a pair of rotating bodies that are located in both end parts of the supporting body to be able to rotate and that control the distance between ends of rotating bodies; a coupling unit that has one side part which is connected with a wire being a tension controlling subject or a bracket which supports the wire and that has the other side part which is located between the rotating bodies; a socket that is located between the end parts of the rotating body and that is coupled to the other part of the coupling unit; a turnbuckle unit that controls the distance between the sockets by rotating and that has a turnbuckle main body which applies tension to the wire; and a transmitting port that is coupled to the coupling unit between the rotating body and the socket, moves toward the turnbuckle unit by being pushed by the rotating body, and applies pretension to the wire; and a rotating control device that is connected with the other end part of the rotating body and that rotates the rotating body by stretching to change the length thereof. |
