載の電磁式燃料噴射弁装置。[Scope of Claim for Utility Model Registration] (1) An electromagnetic fuel injection valve device that is installed in the intake passage of an engine and opens a valve body to inject fuel into the intake passage, which is substantially pipe-shaped and has a flange on the base end. a nozzle body support cap made of a pressed metal part which is formed in a shape, houses the nozzle body inside the tip side and is fixed by caulking, and a pipe material made of a magnetic material and a bearing ball that opens and closes the fuel injection hole of the nozzle body. a valve body formed by joining an armature at the distal end side of the armature, the distal end of which is provided with a notch through which fuel passes; a spacer slidably holding the outer periphery of the armature of the valve body; and a pipe material made of a magnetic material whose distal end face faces the proximal end face of the armature with a predetermined distance therebetween, and whose distal end face faces the proximal end face of the armature at a predetermined distance. a fuel supply pipe with a fuel filter attached therein; a spring that constantly biases the valve body toward the nozzle body; a spring located inside the fuel supply pipe and fixed to the fuel supply pipe by caulking; a spring holding pipe that adjusts and holds the biasing force of the spring; and a spring retaining pipe that is arranged around the fuel supply pipe and generates a magnetic field when energized to magnetize the fuel supply pipe and move the valve body against the biasing force of the spring. an electromagnetic coil for suction; a coil cap that is a metal press part that covers the outer periphery of the electromagnetic coil, and fixes the nozzle body support cap by caulking the distal end thereof, and fixing the fuel supply pipe by caulking the proximal end; An electromagnetic fuel injection valve device comprising: a resin housing that covers from the tip of the nozzle body support cap to the base end of the coil cap and forms a terminal portion of the electromagnetic coil. (2) At least one of the caulked portions of the nozzle body and the nozzle body support cap, the nozzle body support cap and the coil cap, and the coil cap and the fuel supply pipe are fixed by welding such as laser welding. 1. The electromagnetic fuel injection valve device according to 1.
