する自動車用排気管継手。[Scope of Claim for Utility Model Registration] In an automobile exhaust pipe joint consisting of a downstream exhaust pipe, an upstream exhaust pipe, and a sealing body disposed between them, one exhaust pipe has a morning glory-shaped structure at its end. A spherical portion with an enlarged diameter and a cylindrical portion connected to the spherical portion are formed, and the cylindrical portion has a male thread portion and at least two tongue portions formed on its outer peripheral surface,
The other exhaust pipe is formed with an annular flange part leaving the pipe end on the exhaust pipe side, and the pipe end has a circular hole on the inner surface, a partially convex spherical part on the outer surface, and a large part of the partially convex spherical part. A seal body having a flat part on the diameter side fits the circular hole into the outer circumferential surface of the tube end, makes the partially convex spherical part slide into contact with the concave spherical part on the inner surface of the spherical part, and connects the flat part to the annular flange part. The cylindrical part has a cylindrical part having a female threaded part on its inner surface, a cylindrical part having a female threaded part on the inner surface, at least two windows on the periphery of the cylindrical part, and a diameter-reduced part at the end of the cylindrical part. A spring receiving member having an annular stopper portion is screwed and fixed so that the window portion corresponds to the tongue portion, and the tongue portion is folded back to protrude into the window portion, and the flange portion and the spring receiving member are fixed. An exhaust pipe joint for an automobile, characterized in that a conical coil spring is disposed between a spring receiving member and an annular stopper part.
