ABSTRACT OF THE DISCLOSURE A power transmission mechanism in which a small rotatable screw thread is arranged symmetrically with a large rotatable screw thread. The pitch and the pitch circle diameter of the large screw thread are the same integer times the pitch and the pitch circle diameter of the small screw thread. The screw thread grooves are connected through ball means and a convenient combination of screw threads provides an input shaft and an output shaft either in parallel or in alignment. This arrangement provides a power transmission mechanism of a compact size and a simple structure with an enhanced ratio of power increase and decrease.
