Abstract:
1. A sealing device adapted to be installed to one of two relatively rotating members and adapted to slidably come into close contact with the other of the two relatively rotating members, the sealing device comprising: a mounting ring fittable to said one member and made of a rigid material; and an elastomeric body attached to said mounting ring, said elastomeric body including a side lip to slidably come into close contact with said other member, wherein said mounting ring includes: said elastomeric body has a rubber step part arranged at one side in the axial direction of said cylinder portion, said cylinder portion and said rubber step part are radially aligned, said side lip has a first height relative to a plane of a radially extending planar end surface in an axial direction of said rubber step part, said cylinder portion has a second height from a plane of an end portion at another side in the axial direction of said cylinder portion to said inward flange portion, said first height being less than said second height, and said end surface in the axial direction of said rubber step part has a radial direction positioning portion, said radial direction positioning portion is an annular convex portion provided on an inner peripheral end portion of the end surface, the annular convex portion protruding in the axial direction relative to the end surface of the rubber step part, and a diameter of an outer peripheral portion of the annular convex portion coincides with an inner peripheral diameter of the reverse portion so that the annular convex portion is adapted to contact a reverse portion of another said sealing device when stacked thereon.
