Note that the same reference numerals in each figure indicate the same or equivalent parts.

Claims

[Scope of utility model registration request]

a coil, a fixed core disposed within this coil,
A movable core disposed opposite to one end of the fixed core, a return spring disposed between the movable core and the fixed core, and the other end of the fixed core having a through hole through which the movable core passes. a yoke that magnetically couples the part to the movable iron core, a rectifier consisting of a case and a rectifier circuit housed in the case, which converts alternating current into direct current and supplies power to the coil, and energizes the coil. When this occurs, the movable core is attracted to the fixed core against the force of the return spring, and when the power is not energized, the movable core is separated from the fixed core by the return spring, and a portion of the movable core is removed from the through hole. In the electromagnet device that protrudes to the outside of the yoke, the case of the rectifier is provided with a recess for accommodating the part of the movable core when the coil is not energized, and the case is inserted into the through hole of the yoke. An electromagnet device, characterized in that the electromagnet device is attached to an outer surface of a wall having a wall such that the recess is aligned with the movable iron core.
