Abstract
A sealing device has a single rubber seal member provided with two oppositely directed seal lips which form a V-shaped cross-section and which are in contact with a spherical surface. Grease is filled in the V-shaped space. A portion of an outer fitting member protrudes inwardly to hold the seal member in place.
