Continuously variable transmission for vehicle

A continuously variable transmission for a vehicle comprising:

• a variator including;
• a primary pulley,
• a secondary pulley, and
• an endless annular member wound around the primary pulley and the secondary pulley,
• the secondary pulley being provided with an urging member configured to generate an urging force in a direction in which a groove width of the secondary pulley is decreased, and
• a pressure receiving chamber of the primary pulley being sealed so that an oil is remained after a stop of a supply of the oil to the pressure receiving chamber of the primary pulley, and
• an amount of the oil remained after the stop of the supply of the oil to the pressure receiving chamber of the primary pulley being set so that when a vehicle speed becomes equal to or greater than a predetermined vehicle speed when the vehicle is towed, a transmission gear ratio of the variator is brought to a high side of a lowest transmission gear ratio, and to a low side of a middle transmission gear ratio, by a centrifugal hydraulic operation of the oil stored in the pulley pressure receiving chamber of the primary pulley.
