Abstract
A toroidal-type continuously variable transmission, includes: an input shaft; a pair of mutually opposed input and output disks disposed side-by-side in an axial direction of the input shaft; a pressing mechanism pressing said input disk toward said output disk; a hollow shaft disposed around an outer periphery of the input shaft concentrically with the input shaft, and connecting the pair of input disks to each other; an oil hole formed in a no-penetrating portion of the input shaft where the input shaft does not penetrate through the hollow shaft, and opened on an outer peripheral surface of the no-penetrating portion; and, an oil passage formed between an inner peripheral surface of the hollow shaft and an outer peripheral surface of a penetrating portion of the input shaft where the input shaft penetrates through the hollow shaft.
