ABSTRACT:
A toroidal type continuously variable transmission intended to prevent an increase in weight of the rear end portion when constructing a automobile transmission and restrain vibrations and noised during an operation. An input shaft is rotated by a crankshaft of an engine through a gear transmission mechanism provided at the front end. The rotations of this input shaft are transmitted to input disks via a driving gear, a driven gear, an external rotary cylinder, cam plates and rollers. Power rollers rotate with rotations of the input disks. The rotations of the power rollers are transmitted to an output shaft via output disks, whereby the output shaft is rotated.
