ABSTRACT:
A toroidal type continuously variable transmission which is arranged such that a pair of toroidal transmission mechanisms are disposed around an input shaft connected to an engine. A forward-reverse switching device is located around the first shaft between the engine and the toroidal transmission mechanism. A control valve assembly is disposed around the forward-reverse switching device relative to the input shaft. Therefore, the needed space for the transmission is reduced, and the responsibility of controlled hydraulic pressure to each element is improved.
