Claims (1)

[Scope of utility model registration request] A coaxial coaxial device in which a plurality of channels of windings are arranged on the inner circumferential surface of a cylindrical outer core, and a plurality of channels of windings are arranged on the outer circumferential surface of a cylindrical inner core of a size that can be inserted into the outer core. In the type rotary transformer, a through hole is formed in the inner core to receive both ends of the winding for each channel winding, and a lead-out groove is formed inside the cylinder of the inner core, and a conductive material is provided in the lead-out groove. A coaxial rotary transformer characterized in that the winding is embedded and both ends of the winding are connected to the conductive material.
