Also, a plurality of connecting portions are selected from these connecting portions, and the connection configuration shown in the first or second embodiment may be used in the selected connecting portions. For example, the connection configuration shown in the first or second embodiment may be used in the connecting portion between the vacuum vessel 2 and the casing 3 and the connecting portion between the casing 3 and the base 10, or may be used in the connecting portion between the vacuum vessel 2 and the casing 3 and the connecting portion between the casing 8 and the casing 9, or may be used in the connecting portion between the casing 8 and the casing 9 and the connecting portion between the casing 3 and the base 10.
