Claims

[Scope of Claim for Utility Model Registration] A movable device made of a magnetic material disposed so as to be freely displaceable in the longitudinal force direction and forming a fitting part, a magnetic pole face, and a magnetic flux receiving part from one end to the other end. A type driving means having an iron core, a fitting part extending in the longitudinal direction of the movable iron core and being fitted with the movable iron core, and an opposing part facing the magnetic pole surface of the movable iron core, and the type driving means is inserted. a fixed iron core having an insertion hole that communicates with the movable iron core; a coil wound around the outer periphery of the movable iron core; and a first yoke that surrounds three sides of the coil and has an opening portion sandwiching the magnetic pole surface of the movable iron core. a second yoke magnetically coupled to the open end of the first yoke and having an insertion hole through which the movable core is inserted; and a return means for biasing the movable core in a direction away from the fixed core. An electromagnetic device comprising:
