Zusammenfassung:A continuously variable transmission includes: a first pulley and a second pulley each including a fixed pulley and a movable pulley; and an endless member wound around the first pulley and the second pulley, wherein the continuously variable transmission continuously changes a speed ratio by controlling a thrust of the movable pulley with a hydraulic pressure, the thrust of the movable pulley is made smaller as a rotation speed of the first pulley decreases, and when the rotation speed of the first pulley is lower than a predetermined rotation speed, the thrust of the movable pulley in a case where the speed ratio is on a Low side of the predetermined speed ratio is not made smaller than the thrust of the movable pulley in a case where the speed ratio is on a High side of the predetermined speed ratio.
