Abstract
The disclosed lever-type gear works on a variable transmission ratio, with the degree of transmission being respectively dependent on the position of the levers and the position of the roller element between the levers. According to a preferred arrangement, the gear can be so designed as to provide a state of indifferent equilibrium once a force F.sub.P is applied to the associated lever by a rod located on the driving side, which force F.sub.P changes along with the stroke s.sub.p of the rod while a constant force is applied to rod applying force to the other lever, irrespective of the stroke s.sub.M thereof.
