PROBLEM TO BE SOLVED: To provide a spherically zonal seal body not generating noise caused by a stick slip or the like even in generation of force in a direction perpendicular to a pipe axis or force in a torsional direction to provide a comfortable automobile not imparting discomfort to a driver or the like. SOLUTION: In this spherical pipe joint 2 using the spherically zonal seal body 1, an upstream-side exhaust pipe 3 and a downstream-side exhaust pipe 4 are oppositely disposed with a gap formed between respective pipe end parts 5, 6, the pipe end part 5 of the upstream-side exhaust pipe 3 is fastened by the inner circumferential face 9 of an annular body 8 and is inserted through a through hole 11 of a seal body 10, an annular end face 12 of the annular body 8 abuts on a flange member 7 together with a large external diameter annular end face 13, the pipe end part 6 of the downstream-side exhaust pipe 4 is fixedly provided with a recessed spherical seal seat 15 slidably contacting with a partially projecting spherical peripheral face 14, and both the exhaust pipes 3, 4 are connected by a press means 16 such that a relative angle is freely displaceable.
