In the load sensing timer mechanism of the fuel injection pump, a regulation valve is provided in the middle of the hydraulic pressure relief passage that releases the internal pressure of the pump to the low pressure side of the feed pump to adjust the hydraulic pressure sent from the feed pump according to the engine speed, The passage from inside the pump is opened to the piston sliding surface of the regular valve, and the opening and the feed pump are connected to the piston of the regular valve only at the piston position when the engine speed is in the middle speed range. A communication passage is provided that communicates with the relief passage to the low pressure side, and the outer circumferential surface of the piston closes the opening when the piston is in a high engine speed range above a predetermined value and a low engine speed range below a predetermined value. An injection timing control device for a diesel engine, characterized in that the piston is configured to block the hydraulic pressure relief passage.
