Abstract: 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.

Abstract: A failure detect device detects the presence of a failure in a peripheral member of a rotary shaft by analyzing a vibration generated in a device provided with the rotary shaft when the rotary shaft is rotated. A vibration detection unit detects the vibration of the device, and a rotation speed detection unit detects a rotation speed of the rotary shaft. An analysis unit calculates a frequency spectrum of the vibration of the device and determines an actually measured vibration level at each vibration order by dividing a frequency component of the calculated frequency spectrum by the rotation speed of the rotary shaft. A detection unit detects the presence of a failure in the peripheral member on the basis of the actually measured vibration level at each vibration order.
