Claims

[Claims for Utility Model Registration] 1. A casing having a fuel inlet, a fixed core housed in the casing, an excitation coil, and when the excitation coil is attracted by the fixed core and de-energized when the excitation coil is energized. a valve member comprising a movable iron core separated from the fixed iron core; a valve seat member disposed near the fuel inlet and having an opening opened and closed by a valve body at the tip of the valve member; a nozzle member having a mouth, and by fitting the nozzle member to the tip of the caning, the fixed position of the valve seat member within the casing is selectively set, and the valve stroke of the valve body is controlled. In the electronically controlled fuel injection valve, one or both of the outer wall of the valve seat member and the opposing inner wall of the casing that accommodates the valve seat member have tapered side surfaces to prevent leakage between the two side surfaces. An electronically controlled fuel injection valve adjustment device that includes a retaining ring. 2. The device according to claim 1, wherein the valve seat member has a truncated conical shape. 3. The device according to claim 1, wherein the leak-proof ring is a synthetic resin 01J ring.
