Claim 3:
4. A sealing device disposed between an inner member and an outer member that rotate relative to each other, the sealing device acting to seal a gap between the inner member and the outer member, the sealing device comprising:
a first sealing member comprising a cylindrical mounted part adapted to be mounted to the outer member, and an annular part extending radially inward from the cylindrical mounted part toward the inner member, and
a second sealing member comprising a sleeve adapted to be mounted to the inner member, a flange extending radially outward from the sleeve and facing the annular part of the first sealing member, and a cylindrical protruding portion made from an elastic material extending along an axial direction from the flange and disposed radially inside the cylindrical mounted part of the first sealing member,
the cylindrical mounted part of the first sealing member comprising an inner peripheral surface on which multiple retaining protrusions made from an elastic material are formed circumferentially, the multiple retaining protrusions being arranged at intervals in a circumferential direction,
the cylindrical protruding portion of the second sealing member comprising an outer peripheral surface on which a circumferential groove extending continuously in a circumferential direction is formed, the multiple retaining protrusions of the first sealing member being placed within the circumferential groove,
the cylindrical protruding portion of the second sealing member comprising an end portion opposite to the flange, the end portion comprising an outer peripheral edge comprising an end protrusion protruding radially further outward than the circumferential groove, the end protrusion extending continuously in a circumferential direction, and
wherein each of the multiple retaining protrusions comprises a first inclined surface located opposite to the annular part, the first inclined surface has an inclination angle relative to a cylinder centered on an axis of the sealing device being less than or equal to 60 degrees.
