Abstract
PURPOSE: To prevent breaking of coils or generation of layer short-circuiting thereof by supporting a protective member of a synthetic resin provided at the outer part of the coil with a gap by flanges formed at both ends of a bobbin.
CONSTITUTION: At both ends of a cylindrical bobbin 4 made of a synthetic resin there are integrally formed ring-shaped flanges 4a and 4b, and a coil 5 is wound between both flanges. At the outer part of the coil 5 there is provided a protective member 6 made of a cylindrical synthetic resin, and the protective member 6 has a bottom surface 6b having a hole 6a, the diameter of the hole 6a being set equivalently to the outer diameter d of the bobbin 4. The bobbin 4 is inserted into the protective member 6, whereby the outer peripheral ends of flanges 4a and 4b are fitted in the inner peripheral surfaces of the protective member 6, and a gap is held between the coil 5 and the protective member 6. By this organization, breaking of the coil or layer short-circuiting thereof can be prevented.
