Abstract
PURPOSE: To enable to install easily in a peripheral groove, with good holding property after the installation and decrease the maintenance cost by a method wherein a ring shape thin metal plate is imbedded in the ring shape elastic member to be used for rotatably sliding large bored sealing device.
CONSTITUTION: The ring shape thin metal plate 12 is imbedded in the elastic member 11 made of synthetic resin or the like to be used as a sealing material. According to the construction described above, the ring shape elastic member 11 can easily be installed in the peripheral groove due to the rigidity of the metal plate without any necessity of using jig for the installation and have a good holding property the installation. The sectional form of the elastic member is solid, and is provided with a member projecting inwardly in cheuron shape, a member the elastic deformation thereof is enlarged by providing a hollow part 21 on its protrusion, and an annular tongue piece 14 installed on the outer periphery of the elastic member and the like. In the above mentioned configuration, the sealing characteristic at the surface where the outer tube 2 and the inner tube 3 overlap each other is enabled to be enhanced.
