Claims

[Scope of utility model registration request]

an excitation coil, a plunger movably inserted through the excitation coil and provided with armature plates at both ends of the exterior of the excitation coil, and a plunger provided on both sides of the excitation coil with both ends inside the armature plates. a pair of inner yokes facing each other, a pair of outer yokes disposed outside these inner yokes with both ends facing the outside of the armature plate, and interposed between an intermediate portion of the inner yokes and the outer yokes. permanent magnets with different magnetic poles facing each other through the armature plate at both ends; and an edge of the armature plate provided near the central axis of the plunger at a contact surface between the armature plate and the inner yoke or the outer yoke. A polarized electromagnet device equipped with a regular plate with a gap on the side.
