PURPOSE: To miniaturize the size, lighten the weight, and reduce the cost of a tension adjustment device by a lever by providing a means for temporarily connecting at least a nut acting mutually with an element connected to an interlock means in a pedestal of a connecting rod. CONSTITUTION: A lever 3 has a connecting rod member having at least a pedestal 4 formed thereon, and the pedestal 4 has means 7a, 7b temporarily connecting at least a nut 5 acting mutually with an element 6 connected to an interlock means. When this assembled component is thrust in the pedestal 4 after the element is attached to the nut 5, the assembled component is fitted to the pedestal 4 by inclined faces 7a, 7b, or the connecting means. After that, the tension is adjusted by the operation of the lever 3. |
