PROBLEM TO BE SOLVED: To obtain a fuel injection valve having a compact structure, and finely atomizing fuel spray.SOLUTION: In a fuel injection valve 1, an end surface of an injection hole plate 13 has a swiveling chamber 19 formed on the outer side in a diametrical direction than a valve seat opening portion 12b, a first swiveling passage 18a in which a downstream side end portion leads fuel into an area of the swiveling chamber 19 on a close side to a valve seat center axis 12c side from a circumferential direction about the valve seat center axis 12c to an injection hole center 14a, and a second swiveling passage 18b in which a downstream side end portion leads fuel into an area of the swiveling chamber 19 on a side far from the valve center axis 12c from the circumferential direction about the valve seat center axis 12c to the injection hole center 14a.SELECTED DRAWING: Figure 5 |
