A single direction driving device is provided in the cross coupling driving system of a nonharmonious unequal ratio complex number wheel train. By the mutual action of the driving of the restricting torsion driving device, there is provided an output ratio with different speed ratios following the ratio of transmission of the load automatically, or there is provided the output ratio with different speed ratios once obverse or reverse turning is produced and applied to various driving structures. The structure comprises the installation of the driving wheel train with different speed ratios to be able to slide along with the torsion between two driving axles and a driving wheel train providing the function of single direction drive.
