Claims

[Scope of utility model registration request]

In a solenoid in which a movable shaft is inserted into a through hole formed between two poles of an electromagnet including an iron core, a pair of movable shafts each formed substantially larger than the through hole are provided at both ends of the movable shaft. A solenoid characterized in that permanent magnets are fixed with their magnetic polarities facing each other.
