装置。 A cylinder connected to a fuel supply path, a plunger that is slidable inside the cylinder, and a fuel injection port are connected, and the fuel compressed by the plunger is sent to the fuel injection port, and injection is terminated. Sometimes, the plunger includes a flow path for sending the remaining fuel back into the cylinder, and a discharge path that is connected to the cylinder and returns the returned fuel to the fuel supply side at the end of injection. Before fuel injection, the fuel from the fuel supply path is sent to the flow path side, and the fuel from the flow path side is sent to the flow path side immediately after the end of fuel injection until the plunger returns to the position before fuel injection. A fuel injection device characterized by being provided with a through hole for discharging air into a discharge path.
