Abstract
A toroidal type continuous variable transmission system to be used as a transmission of an automobile comprises: an input shaft rotatably actuated by means of a drive source; an output shaft for acquiring power stemming from rotation of the input shaft; a variator which is interposed between the input and output shafts and includes a pair of input disks which rotate on the basis of rotation of the input shaft, a pair of output disks which are provided in a coaxial relationship with the input disks and rotate in synchronous with each other, and power rollers which are provided between the input and output disks while remaining in contact with the disks and which rotate at an angle; a planetary gear mechanism which is interposed between the input and output shafts and includes a sun gear, a ring gear provided around the sun gear, a plurality of planetary gears which are provided between the sun gear and the ring gear so as to be rotatable, and carriers supporting the planet gears; a pressing mechanism which presses the input or output disk against the output or input disk by way of the power rollers; a first power transmission mechanism which transmits the rotation of the output disk…
