Claims

[Claims for Utility Model Registration] (1) A bobbin with flanges formed at both ends of a hollow winding body around which a winding is wound, and one leg extending from both flanges into the hollow winding body. In the coil device having an inserted U-shaped core, a displacement prevention portion is provided on the contact surface of the U-shaped core with the flange of the bobbin to prevent displacement of the attachment posture to the bobbin. Characteristic coil device. (2) A bobbin in which a flange and a protrusion are formed at both ends of a hollow winding body around which a winding is wound, and a U in which one leg is inserted into the hollow winding body from both flanges. In the coil device having the U-shaped core, the contact surface of the U-shaped core with the flange of the bobbin is provided with an inclined displacement for preventing inclined displacement of the legs of the U-shaped core within the hollow winding body. A coil characterized in that a rotational displacement prevention portion for preventing rotational displacement of the leg within the hollow winding trunk is provided on the contact surface between the prevention portion and the convex portion of the U-shaped core. Device.
