A stepless transmission 1 is provided for preventing drive wheels from being driven despite the driver's intention during vehicle deceleration. A control device 40: when the required drive force of the vehicle is 0, controls the output rotational speed Ne of a travel drive source 50 to be Ne2, and controls the transmission gear ratio i of the transmission 1 so that the transmission 1 in the case where the Ne is Ne1 changes from a first state to a second state; and when the vehicle speed V is less than a boundary speed Vgn, controls the ratio i to be a state maintaining transmission gear ratio ign that enables the first state to be maintained even during vehicle deceleration. In the second state a rotational drive force is transmitted from an input shaft 2 to an output shaft 3. In the first state the transmission is prevented.
