PROBLEM TO BE SOLVED: To provide a fuel injection device for a motorcycle capable of improving a hot re-startability and increasing the fuel control accuracy of a fuel injection valve. SOLUTION: This fuel injection device comprises a fuel distribution pipe C to which the fuel injection valve J is fitted, a closed fuel chamber A in which a fuel pump P is storably disposed, and a pressure regulating valve B. The fuel chamber A and the pressure regulating valve B are integrally disposed above the fuel distribution pipe C. The discharge hole 11 of the fuel pump P communicates with the fuel distribution passage 50 of the fuel distribution pipe C through a fuel discharge hole 25, a fuel supply pipe 72, and the pressure regulating valve B, and a return fuel pipe 73 of the pressure regulating valve B communicates with the inside of the fuel chamber A. The fuel injection device is disposed under a fuel tank T. The fuel tank T communicates with the fuel chamber A through a fuel inflow pipe 70, and the fuel chamber A communicates with the tank T through a vapor vent passage 71. COPYRIGHT: (C)2007,JPO&INPIT
