  "textContent": "It is an object of the invention to provide a fuel injection valve in which the uniformity of a swirl flow in the circumferential direction is enhanced. The fuel injection valve (1) of the invention includes a swirling chamber (22a-22c) having an inner wall surface comprised of a helical curve and a passage (21a-21c) for swirling for guiding fuel into the swirling chamber (22a-22c). The fuel injection valve (1) is so formed that the center of a circle as the basis of the helical curve and the center of a fuel injection hole (23a-23c) open in the swirling chamber (22a-22c) agree with each other.",
