Claims

[Scope of utility model registration request]

A container made of a non-magnetic material, which has an iron piece at one end and has a plunger made of a magnetic material inside thereof so as to be movable to one side of the iron against braking oil and a compression spring; An excitation coil that magnetizes the plunger and moves it to one side of the iron, and a substantially L-shaped joint that fixes the container on the horizontal part and rotatably supports the movable iron piece that is attracted to the iron piece at the upper end of the vertical part. In the electromagnetic device, the electromagnetic device includes an iron, an output piece protruding downward from the base side end of the movable iron piece on the outer surface side of the vertical part of the yoke, and a tension spring that separates the movable iron piece from the iron piece. An electromagnetic device characterized in that the upper end of the piece is open, and the output piece and the base side end of the movable iron piece are integrally formed at the side of the output piece.
