PROBLEM TO BE SOLVED: To achieve a configuration providing accelerating force required for avoiding risk even during traveling with a manual gear shift mode selected. SOLUTION: In this continuously variable transmission, a manual gear shift function is provided for adjusting a gear ratio based on operation by a driver to any one of values in a plurality of stages as predetermined gear ratios mutually different, and an automatic gear shift function is provided for automatically adjusting the gear shift ratio according to an operating condition at that point without being based on the operation by the driver. A function is provided for automatically adjusting to the gear ratio that determined as the optimum gear ratio according to vehicle speed at the time and the amount that an accelerator pedal is depressed, even if the driver does not change the gear ratio to a deceleration side based on the manual gear shift function when the amount that the accelerator pedal is depressed is suddenly increased with any shift stage of the plurality of stages selected based on the gear shift operation by the driver and the gear ratio adjusted to a gear ratio corresponding to the shift stage.
