ず）に供給することが可能である。 The general structure of a conventional rotary transformer is shown in FIGS. 1 and 2. A primary coil 1 is fixed to an outer core 2, and the laminated outer core 2 is fitted with bolts (not shown) in tightening holes 3. are threaded through and tightened together by tightening nuts (not shown). Furthermore, a screw hole 4 is drilled in the outer core 2, a hole 6 that matches the screw hole 4 is drilled in the bearing support 5, and a screw (not shown) is screwed into the screw hole 4 through the hole 6. As a result, the outer core 2 is fixed to the bearing support 5. Bearing support 5
rotatably supports a hollow rotating shaft 7 via a bearing 8. Due to the rotation of the rotating shaft 7, the inner core 9 and the secondary coil 1 fixed to the rotating shaft 7
0 rotates. Therefore, the secondary voltage generated in the secondary coil 10 can be easily supplied to a rotating load (not shown).

いる。 However, in the conventional structure, the outer core 2 of the primary coil 1 is fixed, the secondary coil 10,
Since the inner core 9 and the bearing support 5, which determines the position of the rotating shaft 7, are fixed with screws, the positions of the screw holes 4 and 6 cannot be corrected once they are formed. Therefore, it is impossible to modify the positional relationship between the outer core 2 and the bearing support 5.
Therefore, there is a problem in that the accuracy of the mutual positional relationship between the primary coil 1 and the secondary coil 10 deteriorates.

となつている。 Furthermore, when manufacturing based on this structure, it is necessary to fix the laminated outer core 2 using the tightening holes 3, and after assembling it with the primary coil 1, machining is necessary to drill the screw holes 4. That is, since parts processing is required during the assembly process, the processing time is also long, and the secondary coil 10 when drilling the screw hole 4 is
There are also problems in the manufacturing process, such as the need to be careful in handling, which is a factor that increases manufacturing costs.
