Abstract:
A continuously variable transmission includes a transmission belt including a plurality of elements each including a pair of pillar portions and a ring arranged between the pair of pillar portions of each of the plurality of elements, and a lubricant supply portion arranged on an inner side of the transmission belt in a radial direction. Each of the plurality of elements further includes a pair of rocking edge portions formed away from each other in a width direction, and a non-contact portion extending between the pair of rocking edge portions in the width direction along a saddle surface. A clearance that communicates the non-contact portion and a region on an inner side in the radial direction with respect to the transmission belt is formed between the elements included in a looped portion of the transmission belt around a first or second pulley.
