Claims

[Scope of utility model registration request]

A pair of fixed yokes that are spaced apart from each other and each have a first magnetic pole part and a second magnetic pole part; A coil that excites the second magnetic pole parts to have the same polarity and excite the first magnetic pole part and the second magnetic pole part to have different polarities, and is arranged opposite to the first magnetic pole part of both fixed yokes. The first fixed yoke has an armature portion arranged such that when the armature portion comes into contact with the first magnetic pole portion of one fixed yoke, the armature portion is separated from the first magnetic pole portion of the other fixed yoke. a movable yoke, and an armature portion opposed to the second magnetic pole portion of both fixed yokes, and when the armature portion contacts the second magnetic pole portion of one fixed yoke, the second magnetic pole portion of the other fixed yoke The magnetic poles are magnetically coupled to a second movable yoke disposed such that the armature is spaced apart from the magnetic pole part of the yoke, and corresponding parts between the first magnetic pole part and the second magnetic pole part of each fixed yoke. The first movable yoke and the second movable yoke are magnetically coupled to each other when the coil is energized. A polarized electromagnet comprising a contact portion forming a closed magnetic path passing through a permanent magnet, both fixed yokes, and both movable yokes.
