<p>A rotary transformer includes a rotary magnetic member (11a), a stationary magnetic member (11b), and a plurality of coils (13a, 13b, 14a, 14b, 16a, 16b). These two magnetic members have respective counter surfaces opposing to each other with a small space (S) interposed therebetween. A plurality of pairs of coil grooves (12a, 12b) opposing to each other for receiving the plurality of coils on the two counter surfaces are provided. At the same time, a plurality of wiring grooves (18a, 18b) are formed so as to cross the coil grooves to join the same. A pair of lead lines extending from one of the coils (13a, 13b, 14a, 14b) disposed in the coil grooves are drawn out outside of the rotary transformer without crossing other coils simultaneously transferring signals in the wiring groove. <IMAGE> <IMAGE></p> |
