ABSTRACT:
A torque transmitting belt spanned between an input and output pulleys including a circumferential groove of a V-shaped cross-section to transmit a torque between the pulleys. The torque transmitting belt is employed in a continuously variable transmission which adjusts the size of V-shaped groove(s) in one or both of the pulleys as a result of the variation of the pressure which forces the belt into groove(s). The torque transmitting belt has an endless carrier spanned between the pulleys and a plurality of torque transmitting blocks which are mounted by the endless carrier so that the blocks may be longitudinally shiftable along the endless carrier. The endless carrier includes a plurality of hoops which are superimposed each other. The endless carrier extends through a groove of the torque transmitting blocks, which has an opening adjacent the inner surface of the pulley. The hoops is designed to have different circumferential length according to its positions within the groove. The circumferential length of the hoop at the lift position of the side facing the opening of the groove is designed to be less than that at the right position within the groove.
