In addition, when fixing (incorporating) the gap device to the storage part, a low melting point glass frit is used, but since it is used only in a small amount only for adhering both joints, the same glass for the insulating space and the body insulator is used. Since the influence of the frit is reduced, the stress due to the difference in the coefficient of thermal expansion is not generated in them, and the yield at the time of glass bonding is improved such that cracks and crevices are not generated, and the productivity can be remarkably improved. Further, a packing-like sealing material 33 made of an inorganic material is interposed between the upper ends of the above-mentioned joints and the lower ends of the small-diameter portions of the spacers adjacent to the joints. Part 2m, 2
It will not flow out from 9b, resulting in a strong joint structure.

1. A hollow structure in which a cylindrical insulating spacer (29) is airtightly closed at both ends and a discharge gap device (28) having a discharge portion is provided in the spacer, and which is formed in a main body insulator. In such a manner that it is housed and fixed in the gap-shaped housing (2h), the inner peripheral wall of the housing of the main body insulator is provided with a joint (2m) projecting inward, and the outer peripheral surface of the insulating spacer is provided. A joint portion (29b) is formed so as to abut the joint portion, and both joint portions are integrally and closely joined through a low melting point glass frit (34), and the upper ends of the both joint portions and a spacer adjacent thereto. A structure for mounting a discharge gap device in a high-pressure cutout with a built-in arrester, characterized in that a packing-like sealing material (33) made of an inorganic material is interposed between the lower end of the small diameter part and the lower end.
