TRANSMISSION BELT

The present invention relates to a transmission belt which can be maintained at the state of external contact as long as possible regardless of the wear of the side surface, by setting the side angleof the element to be greater than the conical bus angle of the pulley to bring the element into an external contact state. Since the side angles of the elements (26a, 26b) are set greater than the conical bus angle of variable pulleys (14, 16), the pressing load of the outer peripheral side portions (A, B) of the side faces (28a, 28b) is greater than the state of the external contact of the innerperipheral side portion, so that, the posture when the elements (26a, 26b) protrude into the variable pulleys (14, 16) is stabilized, thereby improving the power transmission efficiency. Moreover, since the wear of the side surface (28a) (solid line) of the first element (26a) having a wide width is deteriorated, as shown in the left half portion, the side surface of the second element (26b) having a narrow width is obtain
