Claims

[Scope of utility model registration request]

In an expansion joint in which a pipe member and a bellows are connected concentrically in the axial direction and a conductor is insulated and housed inside along with an insulating gas, the pipe member side end of the bellows is placed outside the bellows side end of the pipe member. 1. An expansion joint characterized in that the bellows is externally connected and the outer peripheral surface of the bellows near the end on the pipe member side is surrounded almost entirely by a reinforcing member.
