<p>PROBLEM TO BE SOLVED: To make it possible to prevent the occurrence of metal powder and of disturbing the normal expansion and shrinkage of bellows by providing a construction which is able to assure the motion of bellows body along the guide pin without touching the inner surface of a housing container during the expansion and shrinkage of the bellows. SOLUTION: A guide pin receiver 9 is provided at the outer peripheral portion of an end flange 8 at a free end side of a metal bellows body 1. Also, a guide pin 10 having a length adjusted to the expansion and shrinkage length of the metal bellows body 1 is provided along the expansion and shrinkage direction of the metal bellows body 1 at a flange 7 facing the free end side of the metal bellows body 1 of a housing 6. And the guide pin 10 is assembled by penetrating through the guide pin receiver 9 in a slidable manner. That is, if the metal bellows body 1 expands and shrinks by the expansion and shrinkage of insulating oil inside the termination connecting device, the flange 8 at the free end moves along the guide pin 10 and the expansion and shrinkage of the metal bellows body 1 can be accomplished without touching the inner wall of the housing 6 by the flange 8 at the free end.</p> |
