Abstract
A fuel injection valve includes a soundproofing cover molded out of a rubber-containing soft resin and arranged on the outer periphery of a metal casing. Collision noises and vibrations are absorbed by the soundproofing cover, achieving excellent sound insulation. Moreover, the rubber-containing soft resin is lower in cost, and can be shaped by injection molding, resulting in a reduction in manufacturing cost of the valve.
