Claims

[Scope of utility model registration request]

In an oil-filled electrical device in which a bushing is attached to a tank body cover, the cover portion where the bushing is located is narrowed inward to a predetermined thickness to form a bushing opening having a tapered cylindrical portion at the periphery; A bushing having protrusions formed at intervals equal to the drawing thickness of the cylindrical part is fitted so that the cylindrical part is positioned between the protrusions, and the bushing and the tank body cover are in contact with each other. Oil-filled electrical equipment characterized by having parts that are liquid-tight.
