Abstract:
A belt for a continuously variable transmission, which comprises a metal ring assembly formed of a plurality of endless metal rings laminated one on another, and a large number of metal elements each having a ring slot into which said metal ring assembly is fitted, said belt being wound around a drive pulley and a driven pulley such that pulley-abutment faces of said metal elements but against V-faces of said drive pulley and said driven pulley for transmitting a driving force between both of the pulleys, whereinthe relationship between the thickness of the metal ring assembly and the groove width of the ring slot is established so that a rolling angle of the metal elements provided when a radially outer peripheral surface of the metal ring assembly contacts a radially outer edge of the ring slot in the metal element is in a range of not more than a predetermined rolling angle &agr; and so that a rolling angle of the metal elements generated by a deformation of said pulleys under a condition of low ratio and high load operation is within said range.
