The spherical bearing surfaces on the one connecting flange are in slidable spherical contact with respective spherical portions formed on the annular seal units. Further, both the connecting flanges are made integral over the plurality of spherical joints. The flat bearing surfaces of the other connecting flange confront respective annular seal units so that the flat sides of the annular seal units are brought into contact with the flat bearing surfaces so that the annular seal units can slide thereover in a direction substantially normal to longitudinal axes of exhaust pipes.
