。 The stator on the inner circumferential side is constructed by providing windings in a plurality of coil grooves formed at opposing positions across a small space between the outer and inner circumferences of a cylindrical core coaxially assembled into two inner and outer cylindrical cores. In a coaxial rotary transformer consisting of a transformer and a rotor transformer on the outer circumferential side, the rotor transformer on the outer circumferential side has an inner diameter smaller than the outer diameter of the stator transformer on the inner circumferential side, and the outer circumference corresponds to the coil groove of the stator transformer. a bobbin-type core provided with a coil groove at a position where the coil groove is formed, a winding wire applied to the outer periphery of an insulating ring fixed to the coil groove of the bobbin-type core, and a cylindrical core circumferentially fixed to the bobbin-type core. The inner diameter of the bobbin-type core is then enlarged to a predetermined inner diameter slightly larger than the outer diameter of the stator transformer, and the insulating ring is exposed inside. type rotary transformer.
