Abstract
A continuously variable transmission is obtained by winding, around a drive sheave and a driven sheave, a continuously variable transmission belt in which a plurality of metal elements are stacked and supported on an endless ring. In at least one of the metal elements, flange parts are formed on a head part positioned at an outer peripheral side of the endless ring and a trunk part positioned at an inner peripheral side of the endless ring. The continuously variable transmission is provided with a fluid supply device which, during movement of the continuously variable transmission belt from the driven sheave to the drive sheave, sprayed lubricating oil in a movement direction of the continuously variable transmission belt, towards the flange parts.
