とする燃料噴射ポンプの取付構造。By reciprocating the plunger 3 in the plunger insertion hole 2 formed in the pump body 1, the fuel sucked into the fuel pressurizing chamber 15 formed on the top 3a of the plunger 3 is pressurized to form a cylinder. The fuel injection pump 4 is configured to be able to pump the fuel to the side and to control the amount of fuel injected by controlling the release timing of the fuel pressurized in the fuel pressurizing chamber 15. The body part 21 of the pump body 1 is installed in a state in which it is oil-tightly fitted into a pump mounting hole 29 formed by penetrating the side wall of the engine body in the inner and outer directions, and the pump body 1 is connected to the fuel pressurizing chamber 15 so as to communicate with the fuel pressurizing chamber 15. A mounting structure for a fuel injection pump characterized in that one end of the formed fuel suction hole 18 is communicated with a fuel passage 26 formed through the side wall 25 of the engine body so as to open into the pump mounting hole 29.
