摘要： A gap is provided between a cooling block 22 and a magnetic yoke 20. A cushioning material 25 is interposed in the gap to fix the cooling block 22 relatively to the magnetic yoke 20 by screws. Thus, even when metals having a large difference in tendency of ionization are used in the cooling block 22 and the magnetic yoke 20, the corrosion of the metals hardly arises. Further, the cushioning material 25 is provided in the gap between the cooling block 22 and the magnetic yoke 20, so that an impact or vibration to an anode tubular member 10 can be mitigated and the disconnection and deficiency of the filament of a cathode structural member can be reduced. Further, since a dimensional unevenness of the cooling block 22 or the magnetic yoke 20 can be absorbed by the cushioning material 25, the dimensional accuracy of parts does not need to be improved to make an assembly easy.

摘要： In the capacitor, an insulating structural member 28 is arranged on an earth metal fitting 27. In the earth metal fitting 27, two sets of cylindrical-shaped portions 26 are separately arranged in an interval, and a floating portion 27a is formed. The insulating structural member 28 is arranged opposite to the floating portion 27a of this earth metal fitting 27 in such a manner that both a concave portion 28a and a convex portion 28b are formed on the insulating structural member 28 to be fitted to the cylindrical-shaped portion 26. Since a feedthrough conductor 29 penetrates a through hole 30 of the insulating structural member 28, the earth metal fitting 27, the insulating structural member 28, and the feedthrough conductor 29 are positioned with each other. Then, one opening portion 31a of an insulating case 31 is fitted into the floating portion 27a of the earth metal fitting 27. One opening portion 32a of an insulating cover 32 is fitted on the rear side of the floating portion 27a of the earth metal fitting 27 in such a manner that this opening portion 32a surrounds the feedthrough conductors 29 on another side of the earth metal fitting 27. An insulating resin 33 has been filled in such a way that this insulating resin 33 embeds therein a peripheral portion of the penetration portion of the feedthrough conductor 29.
