。An injection timing adjustment mechanism that adjusts the fuel injection timing using fuel oil pressure corresponding to the engine rotational speed, and a fuel return passage that communicates with the hydraulic chamber through the port of the governor sleeve are provided at the axial center of the governor shaft. a hydraulic control mechanism that delays fuel injection timing by releasing a portion of the fuel in the hydraulic chamber to the fuel return passage to lower the fuel oil pressure in a low load region where the fuel return indicator communicates; , a fuel injection device comprising a control release mechanism that disables the oil pressure lowering function of the oil pressure control mechanism in a high speed region where the engine speed exceeds a predetermined value, the control release mechanism being disposed within the governor shaft. a valve body that is housed so as to be movable in an axial direction and opens and closes the fuel return passage by its forward and backward movements; a spring that biases the valve body in an opening direction; and a spring that applies the fuel oil pressure to one end of the valve body. 1. A fuel injection device for a diesel engine, comprising a hydraulic pressure introduction chamber for biasing the valve body in a closing direction.
