装置。[Scope of Claim for Utility Model Registration] Supplying oil discharged from a hydraulic pump to the actuator of a work machine through an operation valve to drive the work machine actuator and keeping the differential pressure between the discharge pressure of the hydraulic pump and the load pressure constant. In a load sensing device for a hydraulically driven machine that controls a pump flow rate, the discharge pressure of the hydraulic pump is detected at the inlet of the operating valve, and the pump flow rate is controlled so that the differential pressure between the detected pressure and the load pressure is constant. A load sensing device for a hydraulically driven machine, characterized in that:
