Abstract: A sealing device including a sealing device main body 1 mounted on one of two members 101 that rotate relatively, and a seal flange mounted to the other of the two members 102. The sealing device main body 1 is provided with a structure provided with a seal lip 12 slidably connected to a seal flange 22, and a tube part 18 positioned further to the outer side than the seal lip 12. A labyrinth lip 15 is provided on the sealing device main body 1 positioned further to the outer side than the seal lip 12; and, the labyrinth lip 15 extends towards the radially opposite side to the tip end of the seal flange 22 facing the tube part 18 in a radial direction, as the tip end closely faces the seal flange 22 in an axial direction, and a labyrinth gap 3 is formed between the labyrinth lip 15 and the seal flange 22, and the tube part 18.
