5. The sealing device as set forth in claim 1,
wherein the core member comprises a cylindrical portion fitted to an outer circumference of the outer member and a circular plate portion extending inward in a diametrical direction from the end portion on the flange portion side of the cylindrical portion,
the seal body comprises a cover portion covering the cylindrical portion, and
the weir portion is configured to be integral with the cover portion and to be greater in diameter than the cover portion.
6. A sealing device configured to be provided for a mechanical apparatus having an inner member with a flange portion continuously enlarging in a diametrical direction and an outer member rotating relative to the inner member around a shaft of the mechanical apparatus, the sealing device being configured to seal a gap on the flange portion side between the outer member and the inner member by being attached to the outer member, the sealing device comprising:
a core member attached to the outer member; and
a seal body fixed to the core member;
the flange portion having an eave portion extending toward the seal body side;
the seal body having a projecting portion and a weir portion, the projecting portion being positioned inward in a diametrical direction from the eave portion and extending toward the flange portion, the weir portion being positioned outward in a diametrical direction further than the eave portion and extending toward the flange portion, and
the projecting portion and the weir portion overlapping the eave portion in a diametrical direction, the projecting portion and the weir portion being provided adjacent to the eave portion, thereby forming a labyrinth, the labyrinth having a plurality of labyrinth constituting portions folding back along inner and outer faces of the eave portion in a diametrical direction, and the labyrinth being configured to meander.
7. The sealing device as set forth in claim 2, wherein the weir portion is adjacent to the flange portion and the labyrinth further comprises an adjacent portion of the weir portion and the flange portion as a labyrinth constituting portion.
8. The sealing device as set forth in claim 2, wherein the projecting portion is adjacent to the circular plate portion and the labyrinth further comprises an adjacent portion of the projecting portion and the circular plate portion as a labyrinth constituting portion.
