Abstract
One of bolt section or a nut section on a ball screw devices, or nut sections (for example) are connected to gear sections axially movable, while the bolt sections are connected to a stationary element, so that relative rotation is given to the bolt section and the nut section to adjust movable sheaves. Between another of the bolt section or the nut section on the ball screw devices, or the bolt sections (for example) and the stationary element, adjustable retainers are installed without axial move being allowed, and holding apparatus to hold the retainers at required position is installed with the retainers. Due to the above, initial tension and position of the belt are adjusted and determined by varying the nut sections in axial direction for the bolt sections. It is possible to perform this adjustment after the assembly is completed.
