PROBLEM TO BE SOLVED: To suppress incursion of sediment or the like around a floating seal through a gap formed between a fixed body and a rotor.SOLUTION: An elastic body housing space 33 larger in axial size than a gap 22 is formed outside the gap 22 formed between a fixed body side end surface 13E of a fixed side housing 13 and a rotor side end surface 15C of a rotation side housing 15 in a radial direction and inside a labyrinth 32 in the radial direction. In the elastic body housing space 33, an annular elastic body 36 that covers the gap 22 from the outside in the radial direction in the state of being prevented from rotating off from the rotation side housing 15 is provided. In the elastic body 36, a bent part 36C that axially pushes the elastic body 36 toward the fixed side housing 13 is integrally provided. In the outer peripheral surface of the elastic body 36, a slope surface 36E gradually smaller in outer-radial size from the fixed side housing 13 toward the rotation side housing 15 is provided.SELECTED DRAWING: Figure 3
