Claims

[Scope of utility model registration request]

(1) An electromagnetic device main body having a shape in which a coil is wound around the ■-shaped part of the EIE type core and the coil protrudes from the center of both sides in the stacking direction of the EIE type core is installed in a substantially groove having a coil accommodating groove in the bottom plate. The vertical legs of the E part of one and the other side of the stacking direction plane of the EIE type core are inserted into the shaped member so as to be placed on the bottom plate of the substantially groove shaped member, and the electromagnetic device main body has a coil accommodating groove. A substantially flat member is placed over the vertical legs of one and the other E-shaped portion on the other surface of the EIE core in the stacking direction, and the substantially flat member is placed on both side edges of the substantially groove-shaped member. In an electromagnetic device in which both side edges of the member are caulked and fixed, a support means for supporting the E-shaped portion and the first-shaped portion of one and the other of the EIE-shaped cores so that they are at the same height is attached to the EIE-shaped core. An electromagnetic device characterized by being provided on a substantially groove-shaped member side.

(2) The supporting means is a bent piece having the same height as the bottom plate of the substantially groove-shaped member and provided at both ends of the coil-accommodating recessed bottom plate of the substantially groove-shaped member. The electromagnetic device described in section 1).

(3) The electromagnetic device according to claim 1, wherein the support means is a protrusion provided on the outer surface of the collar of the coil bobbin around which the coil is wound, on the substantially groove-shaped member side.
