ルト座に締め付けてカバーを固定したものである。Means for Solving the Problems In order to solve this problem, the present invention provides a planar rectangular cover in an opening of a tank having a rectangular planar shape that accommodates the main body of an electric device. In an oil-filled transformer bolted to a bolt seat provided on the outer wall of the tank, the four corners of the tank are formed in an R shape,
A bolt seat that does not project from the outer shape of the cover is formed in the center of the outer surface of the R-shape to receive the bolt for tightening the tank cover, and through holes are provided in each part of the cover. The cover is fixed by fastening the inserted bolt to the bolt seat.
作用 この構成により、従来のようなカバー締付金具は不要と

実施例 以下、本考案の一実施例について、図面（第１図、第２
図）に基づいて説明する。Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 and 2).
It will be described based on FIG.

ように設けられている。In the figure, 11 is a rectangular tank with a plane shape.
A bolt seat 12 is attached to the center of the outer surface of the individual R-shaped portion of the side wall of 11. Reference numeral 13 denotes a cover, and a through hole 15 through which a bolt 14 is inserted is formed in a rectangular corner portion having a substantially λ shape outside the tank 11R-shaped portion of the cover 13. The bolt seat 12 is provided so as not to project outward from the outer shape of the cover 13.

ト16に締め付けることにより、カバー13をタンク11上端
に押え付け、タンク11の密閉を保つことができる。Therefore, fix the bolt 14 from above the cover 13 to the plain washer.
By tightening the nut 16 attached to the bolt seat 12 through the through hole 15 via the cover 13, the cover 13 can be pressed against the upper end of the tank 11 and the tank 11 can be kept sealed.
なお、図面では示されていないが、タンク11内には変圧
器として必要な部品の他、絶縁油が設けられている。Although not shown in the drawing, in the tank 11, insulating oil is provided in addition to the components necessary for the transformer.

効果が得られる。As described above, according to the present invention, the components for tightening the cover do not project outside the outer dimensions of the cover, and it is not necessary to make the cover larger than before. The external dimensions can be kept small. Further, since the R-shaped portion at the corner of the tank is provided with the bolt seat, the distance between the bushing and the charging portion can be made larger than before, and the effect that the oil-filled transformer can be downsized as a whole is achieved. can get.
