Abstract
A sealing apparatus includes a slinger which includes a cylindrical portion, and radially-extending portions and provided respectively at axially-opposite ends of the cylindrical portion and an elastic member which includes a base portion fixed to a surface of an inner radially-extending portion of a radially-extending core metal member, and a lip portion connected with the base portion. The lip portion is formed by a first axial lip contacting one radially-extending portion of the slinger and a second axial lip contacting the other radially-extending portion of the slinger. The elastic member is formed such that in an axial cross-section, the distance between a cylindrical portion-opposing surface of the elastic member radially opposed to the cylindrical portion and the cylindrical portion is increasing generally uniformly axially outward.
