Abstract
A reel drum is rotatably supported on a board, and a tensioner case is detachably mounted to the board in the vicinity of the reel drum. Wires are extended from the reel drum in directions opposite to each other. A pair of tension rollers pressed onto the respective wires and roller holders rotatably supporting the respective tension rollers are attached to the tensioner case to be allowed to move in directions substantially orthogonal to the respective wires when the wires are tensioned. Moreover, the tensioner case is provided with biasing means to bias the roller holders in directions that the tension rollers are pressed onto the respective wires. The biasing means is a torsion spring. A contact portion of each roller holder which a wire end extended portion of the torsion spring is in contact with has an angle shape with a ridge aligned in a direction orthogonal to the wire end extended portion of the torsion spring.
