A sealing device for a bearing includes first and second annular sealing plates (1, 2) accommodated within an annular end space between inner and outer races (11, 12). Each of the first and second sealing plates (1, 2) is of a generally L-shaped section including a cylindrical (16, 26) wall and a radial upright wall (1a, 2a), and an elastic seal lip element (38). The first sealing plate (1) is secured with the radial upright wall (1a) thereof positioned adjacent respective end faces of the inner and outer races (11, 12), and the radial upright wall (1a) of the first sealing plate (1) has a free end remote from the cylindrical wall (1b) of the first sealing plate (1) spaced a predetermined distance from the cylindrical wall (2b) of the second sealing plate (2) to thereby form a radial gap (4). The radial upright wall (1a) of the first sealing plate (1) also has an outer side face (B) set back inwardly from a free end face (A) of the cylindrical wall (2b) of the second sealing plate (2).
