Sealing device

A sealing device comprising a slinger fixedly fitted onto a rotary member, a core member fixedly fitted into a stationary member, and an elastic seal member attached to the core member, the elastic seal member having a plurality of seal lip portions elastically and slidably contacting with the slinger, thereby sealing a space to be sealed between the stationary member and the rotary member, wherein:

• said slinger has a first fitting cylindrical portion to be fitted onto said rotary member and a flange portion extending in its radial direction from an outer edge of said first fitting cylindrical portion opposite to said space to be sealed, said flange portion defining a terminal end face and two radial faces, said terminal end face being between said two radial faces;
• said core member has at least a second fitting cylindrical portion to be fitted into said stationary member, whose outer end opposite to said space to be sealed is positioned within the inside of said flange portion of said slinger;
• and
• one of said plurality of seal lip portions projects around said outer end of said second fitting cylindrical portion of said core member so as to elastically and slidably contact with said terminal end face of said flange portion of said slinger.
