Claims

[Scope of utility model registration request]

(1) In a DC electromagnet device in which a coil is fixed to a frame via an iron core, a non-magnetic insulating sheet interposed between the iron core and the movable iron piece is connected to a fixing body and a magnetic shielding piece continuous to this body. A core insertion hole and a positioning engagement hole are formed in the main body, a protrusion is formed in the coil bobbin to be inserted into the engagement hole, and the insulating sheet engages the protrusion in the core insertion hole. While being inserted into the matching holes and fixed, the magnetic shielding pieces are folded 1. A DC electromagnet device characterized by being bent to cover the iron core surface.

(2) The DC electromagnet device according to claim 1, wherein the insulating sheet has a fold formed between the main body and the magnetic shielding piece.

(3) The DC electromagnet device according to claim 1, wherein the insulating sheet is made of a wear-resistant material.
