Description

  The present invention relates to an electromagnetic solenoid device that can be easily reproduced.

Although many electromagnetic solenoid devices are used in gaming machines, from the viewpoint of energy saving, the electromagnetic solenoid device is removed from the gaming machine collected from the game store as used, and the removed electromagnetic solenoid device is used again as a product. After checking whether or not it is possible, it is considered to use an electromagnetic solenoid device that can be used for a new game machine. And, as a result of the examination, we examined electromagnetic solenoid devices that became unusable. The electromagnetic coil, core, and plunger were not rusted or scratched, but the yoke was rusted. It turns out that there are many. For this reason, when replacing the yoke with a new one, the conventionally known electromagnetic solenoid device has a structure in which the yoke is formed in a rectangular tube shape surrounding the electromagnetic coil by caulking the two divided yokes together. For this reason, there is a drawback that the disassembly of the two divided yokes is troublesome.
