Abstract:
A belt for a continuously variable transmission having a drive pulley and a driven pulley, the belt comprisinga plurality of metal elements, each metal element having a front main face and a rear main face for being brought into contact with an adjacent metal element, a saddle face connecting the main faces to each other, at least one ring slot in the saddle face, a lower ear surface, a projection extending from one of the front and rear main faces, a recess formed on the other of the front and rear main faces, wherein the projection from an adjacent metal member can be loosely fitted therein, and left and right pulley-abutment faces; at least one metal ring assembly positioned in the ring slot; wherein the belt is adapted to be reeved around the drive pulley and the driven pulley to transmit a driving force between the pulleys in a state wherein the plurality of metal elements are supported by the metal ring assembly in the ring slot; and wherein when one of the metal elements is rolled relative to the metal ring assembly about a lower end of one of said pulley-abutment faces of the one metal element, the outer peripheral surface of the projection comes into abutment against the inner peripheral surface of the recess of an adjacent metal element, before the inner peripheral surface of the metal ring assembly comes into abutment against the saddle face and the outer peripheral surface of the metal ring assembly comes into abutment against the lower ear surface.
