Abstract

PURPOSE:To avoid a looseness or other inferior troubles by uniting a plunger and a rod contacting it inside a solenoid fuel injection valve and an adjuster and other member inside a yoke through an execution of a beam welding. CONSTITUTION:A fuel supply connector pipe 3 having a filter 14 is screwed into a yoke 1 containing a coil 4. An adjuster 11 for regulating a spring pressure of a coiled spring 10 is centered inside the pipe 13. One end of the spring 10 pushes a plunger 6 in contact with a rod 8, which is subjected to the push to make a ball valve 7 in contact with it open or close a nozzle 3. The plunger 6 and the rod 8 and the pipe 13 and the adjuster 11 shifted after adjusting the spring pressure are firmly fixed through a beam welding 26.
