<p>PROBLEM TO BE SOLVED: To provide a rotary transformer which does not deteriorate characteristics if thickness dimension precision of a magnetic body core and a conductive ring is mitigated. SOLUTION: This transformer comprises two pairs of cylindrical magnetic body cores 1a to 1d, 4a to 4d on a coaxial shaft of which one can be rotated, and the other is fixed, and such the magnetic body core is structured that a plurality of ring-like cores are stacked. In this embodiment, undercuts 9a to 9d, 10a to 10d are provided on a stacked face of the stacked magnetic body core, conductive rings 7a to 7d, 8a to 8d are engaged with the undercuts and a confronting face when stacked is only a vertical face of the magnetic body core.</p> |
