Claims

[Scope of utility model registration request]

An input side V-pulley whose pulley width is variably controlled by fluid pressure is provided on the input shaft, and an output side whose pulley width is variably controlled according to changes in the pulley width of the input side pulley is provided on the output shaft. ■ A pulley is provided and a V-belt is hung between both pulleys to transmit power, and the above input side■
In a vehicle using a continuously variable transmission, in which a gear ratio control valve is installed in the fluid path that controls the pulley width of the pulley and is operated by signals from a throttle valve opening sensor and an engine speed sensor, the engine speed sensor and the speed ratio control valve are installed. A manual control unit that variably controls the signal of the engine rotation speed sensor is installed between the control valve and a gear ratio control valve that changes the gear ratio control valve from low to high according to the signal from the manual control unit. A control device for a continuously variable transmission, characterized in that the control device is configured to operate to perform variable control.
