減少によるロータリートランス諸特性の劣化が生じる。Problems to be Solved by the Invention However, in the conventional configuration described above, as shown in FIG. 4B, as the number of channels increases, the width of the outermost effective opposing surface 5 becomes smaller, and as shown in FIG. Furthermore, due to the external force 8 during assembly and installation of the rotary transformer, the end portion 6a of the outermost effective facing surface 5 is damaged, resulting in deterioration of various characteristics of the rotary transformer due to the reduction of the effective facing surface.

is a rotating core, 2 is a stationary core, 3 is a winding concentrically placed around the center of the rotating core, 4 is a winding concentrically placed around the center of the stationary core, and 9 is a winding placed concentrically around the center of the stationary core. The outermost effective facing surface 6 is a predetermined distance between the rotating core 1 and the stationary core 20, and 1o is a damage prevention facing surface having a distance wider than the predetermined distance 6.゛Next, its operation will be explained. As shown in Figure 2,
In this embodiment, before the external force 8 that is about to be applied to the outermost effective opposing surface 9 of the fixed core 2 hits the outermost effective opposing surface 9,
Since it hits the damage prevention opposing surface 10, almost no force is directly applied to the outermost effective opposing surface 9. Further, even if the external force 8 is sufficient to damage the core, the damage-preventing opposing surface 10 absorbs the external force 8 and the outermost effective opposing surface 9 is not damaged. Although the present embodiment describes the case where an external force is applied to the stationary core, the same applies to the rotating core.
