Abstract
A belt for continuously variable transmission, wherein the relationship between the thickness of the metal ring assembly and the groove width of the ring slot is established so that a limit rolling angle &agr; defined as 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 0.7°<&agr;<2.5°. The upper limit value 2.5° of the angle &agr; is set as a rolling angle at which the driving force transmitting efficiency is a predetermined value or more, and the lower limit value 0.7° of the angle &agr; is set as a rolling angle generated following the deformation of a V-face due to an axial thrust on a drive or driven pulley.
