Each port of the pilot valve is connected to a chamber on both sides of the piston, a hydraulic pump discharge circuit, and a drain oil passage so that the piston moves following the spool of the pilot valve. In a variable displacement hydraulic pump discharge amount control device that controls the discharge amount of a hydraulic pump by adjusting the amount of movement of a valve spool, a pushing force is applied to the amount of movement of a pilot valve spool in accordance with the supplied current. A discharge amount control device for a variable displacement hydraulic pump characterized by adjustment using a solenoid.
