Because of the configuration described above, the following problems exist. In other words, since the inside of the stator is covered with a ring-shaped stainless steel plate, which is a metal plate, both ends of the ring-shaped stainless steel plate must be sealed by welding over the entire circumference, and the generation of a slight gap is allowed. Therefore, the welding operation required a great deal of labor and cost. In addition, the member to be welded to the ring-shaped stainless steel plate must also have a shape that can be easily welded,
The structure was complicated and the cost was significantly higher.
