ABSTRACT:
Provided is a belt-drive continuously variable transmission which comprises a pair of drive pulley and driven pulley, and a belt engaged with the pulleys. The belt includes an endless carrier and a plurality of transverse elements closely arranged on the carrier. Each transverse element has an edge and rotatable about the edge in the longitudinal direction of the belt and converging side faces for contact with contact surfaces of the pulleys. Each of the side faces is curved toward each of the contact surfaces in such a manner as to have, when each of the transverse elements is observed in a plan view, such a circular arc that is of a predetermined radius R and has a center located on a straight line perpendicular to each of the contact surfaces and extending through a point at which the edge and each of the contact surfaces meet.
