Abstract
A fuel injection valve realizing improved circumferential uniformity of swirling fuel is provided. The fuel injection valve includes a swirling chamber having an inner peripheral wall whose curvature is gradually larger from upstream to downstream, a path for swirling which, having a fuel flow-in region formed along a valve axis direction, guides fuel to the swirling chamber, and a fuel injection orifice open into the swirling chamber. In the fuel injection valve, the path for swirling is inclined toward the fuel injection orifice formed on a downstream side of the swirling chamber.
