Claim 0:
1. A sealing device disposed between an inner member and an outer member that rotate relative to each other, and that acts to seal a gap between the inner member and the outer member, the sealing device comprising:
a first sealing member comprising a cylindrical part to be mounted to the outer member, and an annular part that extends radially inward from the cylindrical part toward the inner member; and
a second sealing member comprising a sleeve to be mounted to the inner member, and a flange that extends radially outward from the sleeve, the flange facing the annular part of the first sealing member,
the first sealing member comprising at least three axial lips made from an elastic material that extends from the annular part toward a surface of the flange that faces the annular part,
wherein the at least three axial lips comprise an outermost lip, an intermediate lip, and an innermost lip,
a height of the outermost lip is greater than a height of the intermediate lip such that an interference between the outermost lip and the second sealing member is greater than an interference between the intermediate lip and the second sealing member,
the height of the intermediate lip is greater than a height of the innermost lip such that the interference between the intermediate lip and the second sealing member is greater than an interference between the innermost lip and the second sealing member.
