PROBLEM TO BE SOLVED: To provide the structure of a driving unit, which can obtain the silent and effective transmission of rotational torque with being hardly affected by the dimensional variation in an engaging hole disposed in an output shaft and an input shaft, and a connecting shaft of cable both ends. SOLUTION: The cable 66 comprises the connecting shaft 66a whose shape in cross section at right angles in the longitudinal direction is a polygon having sides of the same numbers as the engaging hole 76b at both ends, and twisted so that each side of the polygon becomes a spirally extending exterior in the longitudinal direction. When the connecting shaft 66a is inserted in the engaging hole 76b, the exterior 66b of the connecting shaft 66a and an inner plane 76c of the engaging hole 76b are brought in contact with each other, and elastically deformed so that the connecting shaft 66a is untwisted.
