Abstract

A ring seal contains a core made from an elastic organic polymer and a metal jacket having a U-shaped sectional shape, which jacket surrounds the core to prevent transfer of a substance generated from the core into the sealed space. The seal of the present invention does not release a foreign material into the sealed space, nor does it require a great force for clamping. Accordingly, it is useful as a vacuum seal that achieves miniaturization and reduced weight of a vacuum apparatus. In particular, by making the sectional shape of the metal jacket a U shape, the core can be easily detached and attached for fitting after forming the jacket, and the inside of the jacket can be washed easily.
