Continuously variable transmission provided with a belt (3) and pulley (1,2) capable of interacting with each other at an acute angle (8) under the influence of a coefficient of friction (:), and which belt is suitable for taking both pushing and pulling forces, the ratio between flank angle (8) and the effective coefficient of friction (:tan) in the tangential direction in rotating conditions being such that, measured in radians, the coefficient of friction (:tan) is less than 1.1 times the value of the relevant flank angle (8), but is greater than 0.55 times that value. <IMAGE> <IMAGE>
