Abstract
A sealing device configured to seal a gap on a flange portion side between an outer member and an inner member by being attached to the outer member. A circular plate portion of a metal ring has an extending portion extending opposite to a flange portion. A seal body has a projecting portion and a weir portion, the projecting portion being positioned inward in a diametrical direction from the extending portion and extending toward the flange portion, the weir portion being positioned outward in a diametrical direction from the extending portion and extending toward the flange portion. The projecting portion and the weir portion overlap the extending portion in a diametrical direction, the projecting portion and the weir portion being provided adjacent to the extending portion, thereby forming a labyrinth. The labyrinth has a plurality of labyrinth constituting portions folding back along inner and outer faces of the extending portion in a diametrical direction, and the labyrinth is configured to meander.
