Claims

[Scope of utility model registration request]

a yoke, a core fixed to the yoke, an operating coil wound around the core, an armature that is attracted to the core by excitation of the operating coil, and an operating coil movably disposed close to the core. An electromagnet consisting of a magnetic flux member that is absorbed by the core and reduces the magnetic flux flowing to the armature and the armature when the generated magnetic flux becomes larger than a predetermined value.
