To provide a torque driving system suitable for a cross-winding means-equipped hinge.
A driving device includes two winding cylinders 1a and 1b and a longitudinal directional link element. In the driving device, the link element has an intersection positioned between the winding cylinders. The driving device is installed in the winding cylinder, and also includes contacting two flexible tracks, and an installation supply is formed of an assembly composed of the winding cylinders and the flexible tracks, and prestress is added to a contact point by operation of the link element. The flexible tracks have a spiral shape, and the contact point between the two spiral flexible tracks where the spiral shape is positioned between the winding cylinders, is dislocated from the intersection of the link elements 3a and 3b, and thereby, torque is added by depending on a distance between the contact point and the intersection, and the torque can cause mutual rotation of the installation supplies 12a and 12b.
