PROBLEM TO BE SOLVED: To solve the problem that a conventional bushing structure causes a wire to twist at the connection between the wire and an insulator upon wire connection work, often leading to the twist separation between the wire and insulator, thus raising a concern about artightness. SOLUTION: A return 22 is formed on the part of a mold cone 2 for a wire 3 that is inserted in an insulator 1, and a level difference 13 is formed on the insulator 1. The mold cone 2 is further provided with a covering 21 so as to cover the insulator 1, so that the adhesion area between a bushing and the mold cone 2 is increased to offer a structure avoiding the twist separation. In addition, the contact faces of the insulator 1 and the mold cone 2 are provided with a recession and a projection corresponding to each other, or with recessions against each other, respectively, and an O ring is placed in a gap between such contact faces to be fixed.
