A double cavity toroidal-type containing variable transmission, in which one of two input disks is fixed to an input shaft, the other input disk and an output disk are supported so as to be movable in the axial direction thereof, and the other input disk is energized toward one input disk by a cylinder, and power rollers 66 respectively stored in a pair of cavities are contacted with the input and output disks. The input shaft is allowed to shift in the axial direction thereof, whereas the output shaft is prevented from shifting in the axial direction thereof. A drive gear formed in the output disk and a driven gear formed in the output shaft are respectively composed of double helical gears.
