ABSTRACT:
A metal belt for a continuously variable transmission includes many metal elements assembled to an endless metal ring assembly, and is wound around drive and driven pulleys to transmit a driving force. A retainer comprising an endless resilient member deformable radially is disposed between a lower face of an ear of a ring slot in the metal element and a radially outer peripheral surface of the metal ring assembly. When the metal elements are inclined in such a manner that they are fallen forwards in the vicinity of an exit portion of the driven pulley, the metal ring assembly is prevented from strongly interfering with a lower face of the ear and a saddle face by a buffering action provided when the retainer is deformed radially, thereby preventing the wear of the metal belt to enhance its durability without increasing the processing cost for the metal elements.
