Abstract:
A belt for a continuously variable transmission having a drive pulley and a driven pulley, comprising a metal ring assembly and a plurality of metal elements, each metal element having front and rear main surfaces for contact with adjacent ones of metal elements, said metal elements being supported on said metal ring assembly with the rear main surface of a preceding metal element being in contact with the front main surface of a succeeding metal element, said belt being wound around the drive pulley and the driven pulley to transmit a driving force between the drive pulley and the driven pulley, whereinthe front main surface of said each metal element has protrusions projecting forward therefrom at predetermined locations with respect to laterally opposite ends in a region near a rocking edge of said each metal element, and the rear main surface of said each metal element has at least one flat surface portion, the protrusions contacting the flat surface portion of an adjacent metal element at least at laterally opposite ends in a region near the rocking edge, wherein said flat surface portion is perpendicular to the forward and rearward directions; and wherein said rocking edge of said each metal element permits relative rotation between said each metal element and said adjacent metal element by coming into contact with said adjacent metal element.
