機の遠心圧打消装置。[Claims for Utility Model Registration] By changing the control pressure in the control chamber on one side of the fixed seal carrier and moving the movable flange in the axial direction, the winding diameter of the V-belt is changed, and the winding diameter of the V-belt is changed from the control chamber to the fixed seal carrier. In a V-belt type continuously variable transmission that cancels the centrifugal pressure in the control chamber by causing oil to flow into a centrifugal pressure canceling chamber on the other side of the seal carrier and generating centrifugal pressure in this chamber according to the amount of oil inflow, A centrifugal pressure canceling device for a V-belt type continuously variable transmission, characterized in that an oil inflow passage from a control chamber to a centrifugal pressure canceling chamber is constituted by a valve whose opening degree increases as the pulley rotation speed increases.
