シング。[Scope of Claim for Utility Model Registration] An elastic member that includes a center conductor whose periphery is covered with an insulating member, and an upper insulator tube and a lower insulator tube arranged above and below a mounting flange that surrounds the center conductor, and which are attached to the center conductor. In a bushing with a center clamp structure, which is integrally tightened with the center conductor, a supporting device is installed on the outer periphery of the center conductor, facing the upper end surface of the flange with a slight gap, and either the upper end surface of the flange or the lower surface of the supporting device is attached to the outer periphery of the center conductor. A sealing material is provided, an elastic member is provided in the storage box provided at the bottom of the center conductor, and the upper insulator tube is crimped to the upper surface of the mounting flange via the center conductor using the second elastic member. A bushing characterized in that a lower insulator tube is crimped to the lower surface of a flange via a storage box.
