  "textContent": "A fuel injection valve includes: a nozzle body having a nozzle hole formed in a front edge portion thereof; a spiral flow path that gives a swirling component to a fuel which passes through the nozzle body toward the nozzle hole; and a pre-injection swirl flow generating means that causes the fuel to flow through the spiral flow path before the nozzle hole is opened. The pre-injection swirl flow generating means includes: a needle member that is slidably arranged in the nozzle body, and rises toward a rear edge side of the nozzle body at the time of fuel injection to expand a first gap between an inner circumferential surface of the nozzle body and the needle member; and a valve member that begins movement to the rear edge side of the nozzle body after the beginning of the rise of the needle member to open the nozzle hole. Thereby, the fuel containing a bubble can be injected from the initial stage of the injection.",
