Abstract

PURPOSE:To reduce cross talk, by providing a protruding part between coils, which are arranged on a fixed-side or rotary-side magnetic bodies, as a part of a fixed-side or rotary-side base material in an electrically grounded state. CONSTITUTION:A protruding part 10 is provided between fixed side coils (S coils) 5b and 6b on a fixed side base material 16 in an electrically grounded state. A through hole 11, in which the protruding part 10 is inserted, is provided in a fixed side magnetic body (S core) 3b. When a signal current is made to flow through the S coil 5b, a current, which is generated by the effect of a magnetic field in a rotary side magnetic coil (R coil) 6a, becomes small by the eddy current effect of the fixed side base material 16 including the protruding part 10. Therefore, the current can be made small in comparison with the case when the protruding part 10 is not present. When a short-circuited shorting ring 8 comprising a conductive material is provided between a rotary side coil (R coil) 5a and the S coil 6b, the current can be made further small. A current is generated by the effect of an electric field. In this case since the protruding part 10 is in the grounded state, a potential in the vicinity of the R coil 6b becomes small. The intensity of the electric field becomes small in comparison with the case when the protruding part 10 is not present.
