Abstract
PURPOSE: To obtain a lip seal having a sealing surface of a rubber lip and a sealing surface of a material consisting basically of fluorine plastics disposed side by side to each other, by forming the sealing surface constituting surfaces of the lip in the manner that they extend along substantially the same cylindrical of conical surface in the state that no force is acted to them.
CONSTITUTION: The inner unit of a seal 3 is composed of an outer sleeve 4, flange 5, lip 6, spring ring 7, and ring 8. The output sleeve 5 and the flange 5 are formed by baking rubber on the outside of the ring 8. The lip 6 has sealing surface constituting surface 11, 12 which are formed respectively on a rubber lip 9 and a lip 10 of a material consisting mainly of fluorine plastics. Here, the surfaces 11, 12 are formed such that they extend along substantially the same cylindrical or conical surface when they are set free. When these surfaces 11, 12 are fitted on the outside of a shaft 1, they constitute a sealing surface of the rubber lip and that of the lip consisting mainly of fluorine plastics, respectively, on the outer surface of the shaft 1.
