PROBLEM TO BE SOLVED: To provide an economical bushing for an electric device capable of being easily mounted on a tank of the electric device, economical as a replacement bushing, easily connected with an electric device main body side, and easily replaced. SOLUTION: In this bushing 1 for the electric device, a central conductor 3 is disposed in a polymer insulator tube 10, an upper terminal 4 for connecting the central conductor 3 with a system line, is disposed on an upper end of the insulator tube 10, and a flange is fixed to a lower end of the insulator tube. An adaptor 11 for adjustment is disposed between the flange of a lower end of the polymer insulator tube 10 and the tank 6, the bushing 1 is mounted on the tank 6 of the electric device, and a lower end of the central conductor 3 is connected with the electric device main body side through a connection terminal 7. Further the length dimension of the central conductor 3 can be adjusted by two hollow members 3A, 3B fitted, and the hollow members 3A, 3B are electrically connected by a current collector 3C.
