An input rotation sensor and an output rotation sensor respectively detect the input rotation speed and output rotation speed of the speed change gear mechanism of the automatic transmission, and the inertia phase time measuring means detects the input rotation speed and the output rotation speed of the transmission gear mechanism based on the signals from these sensors. , the line pressure adjusting means measures the time during which the gear ratio represented by the ratio between the input and output rotational speeds is changing, and controls the line pressure during the shifting so that the inertia phase time becomes a target value. In the line pressure control device, the target value is set changeably based on the operation of the user of the automatic transmission, and the line pressure adjusting means is caused to control the line pressure during the gear shift based on the target value. A line pressure control device for an automatic transmission, comprising a target value setting means.
