Claims

[Claims for Utility Model Registration] 1. A ferrite core formed on a disk has a plurality of channel grooves on the - side, a coil is provided in the channel groove, and the - side faces face each other. In the rotary transformer, a concentric annular groove is provided between the channel grooves on the - surface, a plurality of through holes are provided in a part of the annular groove, and a protrusion that engages with the through hole. A core holding ring made of a non-magnetic conductor having a ring member is inserted by engaging the through hole and the protrusion, a ring member made of a non-magnetic conductor is further inserted into the annular groove, and the core holding ring body and the ring member are inserted. A rotary transformer characterized by electrically joining together. 2. Claim 1 of the claims for utility model registration is characterized in that the core holding ring is smaller than the ferrite core, and a recess for the core holding ring is provided on the surface of the ferrite core on which the core holding ring is attached. rotary transformer. 3. A rotary transformer according to claims 1 and 2 of the utility model registration, characterized in that a conductive resin or a conductive adhesive is used instead of the core holding ring or ring member.
