It has been pointed out that the circularity cannot be maintained. On the other hand, the cylindrical member is also an elastic body, and when the stator core is pressed into the inner periphery of the cylindrical member, the cylindrical member is easily deformed. As a result, there is a problem that the roundness or cylindricity of the stator cannot be maintained at a desired accuracy.
