。[Claim for Utility Model Registration] Line pressure control of a continuously variable transmission in which the gear ratio between the driving pulley and the driven pulley is determined according to the ratio of the oil pressure in the cylinder chamber of the driving pulley and the oil pressure in the cylinder chamber of the driven pulley. When the device detects an increase in the rotational speed of the drive pulley, it applies a signal pressure to the line pressure regulating valve to reduce its pressure regulation value, and when it detects a decrease in the rotational speed of the drive pulley, it applies a signal pressure to the line pressure regulating valve. A line pressure control device for a continuously variable transmission, comprising line pressure changing means for applying a signal pressure that increases the pressure regulation value.
