Abstract
The present toroidal-type continuously variable transmission comprises an oil passage formed in an input shaft so as to extend in the axial direction of the input shaft, a plurality of ball spline grooves formed in the outer peripheral surface of the input shaft so as to be spaced from one another at a given interval in the peripheral direction of the input shaft, a plurality of oil grooves not only for connecting together the ball spline grooves but also for guiding lubricating oil along the outer peripheral surface of the input shaft, and two oil holes 1a formed in the input shaft 1 for allowing the oil grooves and oil passage to communicate with each other.
