とする自動変速機のライン圧制御装置。 The pressure regulator valve is equipped with a pressure regulator valve that regulates line pressure, and the engine torque is regulated via a pressure reducing valve on the pressure receiving surface that generates a force in the direction of increasing the pressure regulation value of the pressure regulator valve. In an automatic transmission that controls a pressure reducing valve by supplying a corresponding pressure and introducing a pressure corresponding to a vehicle speed to a pressure receiving surface in the direction of lowering the pressure regulation value of the pressure reducing valve, the pressure reducing valve on which the pressure corresponding to the vehicle speed acts. A line pressure control device for an automatic transmission, characterized in that a biasing force of an auxiliary spring that corrects the pressure corresponding to the vehicle speed is applied to the pressure receiving surface.
