Abstract
A fuel injection device including a valve body having an injection hole-formed part having a plurality of injection holes on the leading end side of the valve body. An injection hole comprises a crossing angle, θ1, between a central axis of the injection hole-formed part and an injection hole axis, and another injection hole comprises a crossing angle, θ2, between the central axis and another injection hole axis. θ2 is larger than θ1. The injection holes are formed such that a distance between the central axis and an inlet surface center of the injection hole is longer than a distance between the central axis and another inlet surface center of the another injection hole. A straight line beyond an outlet surface in the injection hole axis does not intersect with another straight line beyond another outlet surface in the another injection hole axis.
