Abstract

PURPOSE:To prevent an insulating compound from leaking by integrally forming a flange part in a peripheral part of a stress cone, interposing the flange part by a bushing lower part and a lower part metal fixture, and holding air-tightness in the interior of a bushing. CONSTITUTION:A flange part 10, integrally molded by an insulator of EP rubber or the like, is formed in a peripheral part of a stress cone 9. The flange part is interposed by a lower part of a bushing 1 and a lower part metal fixture 4. Thus by interposing the flange part 10 by the lower part of the bushing 1 and the lower part metal fixture 4, the flange part 10 plays a role of packing action to hold air-tightness of the lower part.
