Claims

[Scope of utility model registration request]

It consists of an outer cylinder and a rotating shaft that is disposed inside the outer cylinder via bearings at both ends so as to form an appropriate gap with the inner surface of the outer cylinder, and an insulating layer is provided on the outer surface of the rotating shaft facing the gap. A slip ring is embedded and fixed in the insulator layer so that its peripheral surface is substantially flush with the surface of the insulator layer, and a brush to be in contact with the slip ring is mounted in the outer cylinder by a spring. The outer cylinder is provided with a purge gas introduction hole that communicates with one end of the gap in the axial direction, and a purge gas discharge hole that also communicates with the other end of the gap in the axial direction. A rotating conductive device.
