Abstract
A pipe joint is provided whereby fluid pipelines, such as exhaust pipes, or the like, can be connected hermetically, in such a manner that the relative angle therebetween can vary, while ensuring satisfactory manufacturing precision of the sealing surface of a ring-shaped sealing ring. In a pipe joint,for connecting a first fluid pipeline,and a second fluid pipeline,hermetically, in such a manner that the relative angle therebetween can vary, a ring-shaped sealing ring,comprising an inner circumference sealing surface,having a tapered shape expanding in diameter towards the open end thereof is provided in the connecting section of the first fluid pipeline,, an outer circumference sealing seat,having a partially convex surface is provided in the connecting section of the second fluid pipeline,, in a position confronting said ring-shaped sealing ring,, and pressure connecting means,for causing the inner circumference sealing surface,of the ring-shaped sealing ring,and said outer circumference sealing seat,to contact under pressure, in a slidable fashion, is provided in a region extending across both said fluid pipelines.
