Claims

[Scope of utility model registration request]

A center conductor whose periphery is covered with an insulating material, a mounting flange surrounding the center conductor, and upper and lower insulator pipes arranged above and below the mounting flange are tightened together by an elastic member attached to the center conductor. In the bushing having a center clamp structure, a sealing material is provided on the upper end surface of the mounting flange, and a support device is attached to the center conductor facing the sealing material with a slight gap between the lower part of the lower insulator pipe and the center conductor. A bushing characterized in that two types of elastic members having different spring constants are provided between the bushing and the lower part, and these elastic members tighten the surrounding insulator pipe and the mounting flange.
