装置。[Scope of Claim for Utility Model Registration] A solenoid valve that reduces a predetermined reference pressure to a pressure corresponding to engine torque in accordance with the magnitude of an operating current value based on an engine torque equivalent signal; A line pressure control device for an automatic transmission, comprising a pressure regulator valve that generates line pressure according to engine torque by applying a signal pressure, the solenoid valve and the pressure regulator. A line pressure control device for an automatic transmission, characterized in that a switching means is provided between the solenoid valve and the solenoid valve so that the reference pressure is directly applied as a signal pressure regardless of whether the solenoid valve is activated or deactivated, at least in low speed gears.
