A sealing device inserted into a wheel bearing is provided. The sealing device comprises a first insert body and a second insert body. The first insert body comprises an annular first frame; and a first sealing part coupled to the first frame. The second insert body comprise an annular second frame having a diameter smaller than that of the first frame; and a second sealing part coupled to the second frame. The second insert body is configured to be rotated relative to the first insert body. The first insert body and the second insert body are arranged such that a gap is formed between the first sealing part and the second sealing part. The second sealing part comprises a first surface facing the first sealing part and spaced apart from the second frame in a first axial direction; and a first baffle protruding from a radially outer end of the first surface toward the first sealing part. A first cavity is formed in the gap by the first sealing part and the first baffle. At least a portion of a first cavity passage connected to the first cavity is formed in the gap by the first sealing part, the first baffle and the first surface.
