ABSTRACT:
A continuously variable transmission of a type having a toroidal transmission unit mounted for rotation on a engine torque input shaft and a planetary gear mechanism mounted on an output shaft in parallel to the input shaft to which engine torque is transmitted directly through an output gear fixedly mounted on the engine input shaft and through the toroidal transmission unit, is provided with a thrust generating mechanism mounted on the input shaft and pressed against a toroidal input disk for mechanically generating a axial thrust acting on the toroidal input disk. The thrust generating mechanism is located on the same side of the toroidal transmission unit as the side where the output gear is located.
