Abstract

PURPOSE: To prevent the non-uniform contact of an elastic packing and raise its rigidity, by providing a hermetic chamber in the packing, connecting the chamber to a pressure gas source and providing an elastic substance around the hermetic chamber.
CONSTITUTION: Even if a pouch 2 is compressed or expanded by the swing of structures 11, 13 which rotate relatively to each other, seal surfaces 10-1, 10-2 are always in tight contact with the structure 13 because a pressure gas in the pouch 2 is compressed or expanded. A drag, which acts on the seal surfaces 10-1, 10-2 and the structure 13 because of the rotary sliding of the pouch on the structure 13, is carried well by a seal member 10 of short span and a hard rigid ring 1 embedded in the flexible pouch 2, without distorting the pouch.
