Abstract
PURPOSE:To suppress the dispersion of the fuel injection quantity and obtain the small-sized fuel injection valve by drilling a shaft hole into which the valve rod of the injection valve is inserted from a fuel chamber side on an inner cover member and metal-attaching the edge surface on the fuel chamber side of the inner cover member directly onto the edge surface of an outer box. CONSTITUTION:A shaft hole 5a into which the valve rod 7d of an injection valve 7 is inserted is drilled on the fuel chamber 3b side on an inner cover member 5, and the depth can be easily measured. The edge surface on the fuel chamber 3b side of the inner cover member 5 which forms a measurement standard surface side directly metal-attached onto the edge surface of an outer box 3, and firmly screw-fixed from the back surface by an electromagnetic cover 4. Thus, the distance between the valve seat 6a of the injection valve and the bottom part of the shaft hole 5a which forms the back pressure chamber is hardly given with the influence of the collection error, and the dispersion of the fuel injection quantity can be reduced.
