ース制御装置。In a continuously variable transmission that includes a continuously variable transmission section consisting of a main pulley, an auxiliary pulley, and a drive belt wound between both pulleys, the power transmission and interconnection are equipped with a forward/reverse switching section. Line pressure is always guided to the auxiliary pulley side hydraulic servo device, and line pressure is supplied to the main pulley side hydraulic servo device at least through a speed change control valve that operates in relation to the throttle opening and engine speed. A continuously variable transmission characterized in that when the switching section is switched to the reverse side, the operation of the speed change control valve is restricted in conjunction with the change, so that a low gear with a large gear ratio is always obtained during reverse operation. Reverse control device.
