Abstract
PURPOSE:To prolong the service life of an endless transmission member by controlling the transmission ratio by the first or second hydraulic cylinder on the side where the sliding contact part between the endless transmission member and the first or second V-shaped pulley is separated in the maximum radial direction from the first or second shaft. CONSTITUTION:Since an endless transmission member 11 on the first pulley 9 side is at the closest position to the first shaft 1, the slide contact area between the both edges of the member 11 and the pulley 9 becomes in, and the force with which the pulley 9 holds the member 11 at this position through a conical plate 5 by the pressurized fluid in the space 12 becomes min. Since, in this case, the slide contact area of the member 11 for the second pulley 10 is larger than that of the pulley 9, the transmission ratio can be sufficiently changed by the holding force for the member 11 which is provided by the pulley 10. Therefore, ratio change can be carried out with the smaller force than that in the prior art, and the force applied onto the member 11 in the ratio change can be reduced, and the service life of the member 11 can be prolonged in comparison with the convertional practice.
