In the fuel injection device, the fuel pressure adjustment device is divided into a pressure adjustment chamber partitioned by a diaphragm and a reference pressure chamber set to a predetermined standard value by a coil spring, An inlet provided on the fuel inlet side and a discharge port that opens an on-off valve to recirculate excess fuel when the pressure of the fuel introduced into the pressure adjustment chamber exceeds the standard value of the diaphragm regulated by a coil spring. are provided integrally and in parallel to the casing via a mounting flange, and the inlet and outlet of the fuel pressure regulator can be directly attached to the supply path and return path formed in advance in parallel to the casing. A fuel pressure regulating device characterized by comprising:
