Abstract

A belt means for transmitting torque between pulleys in a continuously variable transmission. The belt means comprises a plurality of abutting hoops superimposed inside of each other, with no clearance being provided between abutting hoops because the outer circumferential diameter of an inner hoop is greater than or equal to an inner diameter of an outwardly located hoop, whereby, the tensile stresses on the innermost hoop are decreased to enhance the durability and increase the service-life of the inner hoop.
