ABSTRACT:
A continuously variable transmission apparatus, has: an input shaft; a toroidal-type continuously variable transmission; a rotation transmission shaft; first, second and third planetary-gear-type transmissions; a first power transmission mechanism; a second power transmission mechanism; a third power transmission mechanism; and, a switching mechanism, wherein the second sun gear and one of the first and third sun gears are rotated together with the rotation transmission shaft to thereby execute the power transmission through the rotation transmission shaft and one of the first and second planetary-gear-type transmissions, and, in a state where the power transmission through the third planetary-gear-type transmission is cut off, in accordance with the control of the transmission ratio of the toroidal-type continuously variable transmission, the output shaft is stopped while the input shaft is rotating.
