戻し機構。A fuel passage is provided connecting a nozzle that opens into the combustion chamber of the internal combustion engine and a discharge port of the fuel injection pump, and the fuel passage includes a valve hole and a housing hole that communicate with each other near the nozzle. The storage section is provided with a valve hole on the fuel injection pump side and a storage hole on the nozzle side, and the valve hole is provided with fuel pumped from the fuel injection pump when the fuel injection pump is operated. The fuel oil is moved toward the accommodation hole by the oil, communicates the valve hole with the accommodation hole, and allows the fuel oil to pass through the accommodation hole. When the fuel injection pump is stopped, the fuel oil is inserted into the valve hole by a push-back spring, and the fuel oil is inserted into the valve hole to open the fuel passage. A fuel oil return mechanism for a fuel injection device for an internal combustion engine, characterized in that a push-back valve is provided for moving fuel oil in a nozzle to an injection pump side.
