CONNECTION STRUCTURE OF EXHAUST PIPE

Japanese Patent JP3426549

B2

PROBLEM TO BE SOLVED: To provide a connection structure of an exhaust pipe, wherein first connection flanges ranging over downstream ends are joined to the outer peripheries at the downstream ends of a plurality of upstream side exhaust pipes arranged in line and second connection flanges ranging over upstream ends are joined to the outer peripheries of the upstream ends of a plurality of downstream side exhaust pipes arranged in line, and a plurality of spherical joints provided between both flanges comprise annular sealing bodies held between both flanges and spherical bearing surfaces formed on one flanges for spherical contact with spherical faces formed on one side faces of the sealing bodies in a slidable manner, thus solving problems on the precision of parts in conjunction of integration in a simple structure while integrating the flanges over the plurality of spherical joints.
SOLUTION: The faces, opposed to the annular sealing bodies Sa, Sb, of the other flange F1 are provided with flat bearing surfaces f1 for the contact of the other side faces s1 of the annular sealing bodies with the axis of the exhaust pipe in a relatively slidable manner in almost perpendicular direction.
