Claims

[Scope of utility model registration request]

A core for a solenoid having a fuel passage formed therein, a magnetic plunger having a passage aligned with the passage and disposed at the tip of the core so as to move toward and away from the core with a minute stroke, and a magnetic plunger provided at the tip of the plunger. a nozzle that opens and closes with the movement of the plunger by a valve body, and a non-magnetic layer on at least one of the surface of the core facing the magnetic plunger and the surface of the magnetic plunger facing the core. An electromagnetic fuel injection device characterized by being integrally formed.
