Abstract:
A friction-type continuously variable transmission includes first to third rolling elements 31 to 33 each of which is annular and is centered on a principal axis J, planetary rollers 20 arranged in a circumferential direction about the principal axis J, support pins 21 arranged to rotatably support the planetary rollers 20, and a planetary roller support portion 22 arranged to support each support pin such that the support pin is capable of inclining in a section including the principal axis J. Each planetary roller 20 includes a recessed portion 230 in the shape of a circular ring in an outer circumference thereof centered on the support pin 21. The first rolling element 31 is arranged to make contact with a rolling contact surface 23 of the planetary roller 20 from one side in a radial direction axially below the recessed portion 230. The first rolling element 31 is arranged to make contact with the rolling contact surface 23 of the planetary roller 20 from the one side in the radial direction axially above the recessed portion 230. The third rolling element 33 is arranged to make contact with the recessed portion 230 of the planetary roller 20 from an opposite side in the radial direction, and is supported to be capable of moving in a vertical direction relative to the planetary roller support portion 22.
