Abstract:
A belt for a continuously variable transmission, in which a pair of left and right ring slots defined in each of a plurality of metal elements are supported on a pair of left and right metal ring assemblies with each formed of a plurality of endless metal rings laminated one on another, respectively, and which is wound around a drive pulley and a driven pulley to transmit a driving force,each metal element comprising: a neck provided between the pair of left and right ring slots, an ear integrally connected to an upper portion of the neck, an element body integrally connected to a lower portion of the neck, a pair of left and right saddle faces formed on an upper surface of the element body to support a lower surface of the metal ring assembly, a pair of left and right V-faces formed at laterally opposite ends of the element body and adapted to contact with the V-groove of said pulleys, and a pair of left and right recesses formed in a lower edge of the element body and depressed upwards, wherein a height Hs of a non-contact portion formed at an upper portion of the V-face and spaced apart from the V-groove is set larger than a height Hsâ€³ of a non-contact portion formed at a lower portion of the V-face and spaced apart from the V-groove, and wherein the height Hs of the non-contact portion formed at the upper portion of the V-face and spaced apart from the V-groove is set larger than the height Hsâ€³ of the non-contact portion formed at the lower portion of the V-face and spaced apart from the V-groove such that the distribution of a bending moment applied to each said saddle face is such that an integration value of a positive bending moment is substantially equal to an integration value of a negative bending moment.
