<p>PURPOSE:To reduce a current produced by influence of electric field, and improve crosstalk, by dividing a magnetic member on the outer peripheral side so as to contain one or more coils, and installing a retaining member which has protrusions and is made of conductive material. CONSTITUTION:A fixed side magnetic member 3b and a rotary side magnetic member 3a are faced on both sides of peripheral gap. Fixed side coils 5b, 6b are arranged on a magnetic member 3b. Rotary side coils 5a, 6a are arranged on a magnetic member 3a. The magnetic member 3a is divided so as to contain one or more coils. A conductive retaining member 10 electrically grounded has protrusions 10a arranged in the respective gaps between the divided magnetic members 3a. Therefore, value of current produced by the influence of electric field among currents produced in a coil independently of original signal transmission can be reduced. Thereby, crosstalk can be improved.</p> |
