Abstract
A belt for a continuously variable transmission includes a rigid ring. A plurality of adjacent rigid first elements are supported on the ring. Each element has first and second surfaces facing forward and rearward of the element in a direction of rotation of the ring, a first locking edge formed at the first surface, and a second locking edge formed at the second surface. The first surface includes a first inclined face extending radially inward of the first locking edge so that a thickness of the element gradually decreases in a radially inward direction, and a first radially outward face extending radially outward of the first locking edge. The second surface includes a second face extending radially inward of the locking edge and a second radially outward face extending radially outward of the second locking edge. The second face is depressed relative to the second radially outward face so that the thickness of the element is smaller at the second face than at the second radially outward face. The second locking edge is located radially outward of the first locking edge and can contact the first surface of the adjacent element. Accordingly, the adjacent elements are inclinable r…
