る。As described above, the power transformer of the present invention comprises a coil wound around a bobbin, an iron core on which the bobbin is mounted, and a spacer arranged between the coil and the iron core. Since a plurality of protrusions are provided on the collar of the bobbin located on both sides of the core and the film-shaped insulating spacers having an L-shaped cross section are arranged between the protrusions, the spacers are positioned on the bobbin. Even after being arranged between the iron core and the bobbin, it does not fall off, and there is an effect that new parts are not required. Further, since the spacer can be slid on the protrusion and disposed inside the iron core, there is another effect that workability is improved and productivity is improved.
