A first member is fitted onto the inner member, and a second member includes a seal lip portion and a core member fitted into the outer member. The first member has an inner diametrical side cylindrical portion, circular plate portion, and outer diametrical side cylindrical portion. The core member has a cylindrical portion and circular plate portion. A first labyrinth portion is formed along the shaft direction in a gap between the outer diametrical side cylindrical portion and the core member cylindrical portion which face each other diametrically. A second labyrinth portion is formed such that an end face on the bearing space side in the outer diametrical side cylindrical portion faces the core member circular plate portion. A diametrical direction length of the end face is equal to or more than 0.6 mm.

Abstract: A sealing structure for a fitting portion where an annular member is concentrically fitted to a cylindrical member to be fitted at a cylindrical part of the annular member is disclosed. The sealing structure is characterized by an elastic annular seal layer integrally provided on the backward end part of the annular member or the cylindrical member in fitting direction, by applying elastomeric agent to the backward end part and hardening it, and the elastic annular seal layer is formed such that it has layer thickness of 5 ?m to 1 mm and is interposed in a compressed state between the annular member and the cylindrical member when said annular member is fitted to said cylindrical member.

Abstract: A sealing device formed to seal between a fixed side member and a rotating side member, comprising a slinger having a fitting cylindrical part fitted to the rotating side member and a flange part formed at one end part of the fitting cylindrical part positioned on the outer side of a sealed portion so as to be extended in the radial direction. A core comprises at least a fitting cylindrical part fitted to the fixed side member. The sealing device is characterized in that one end part of the fitting cylindrical part positioned on the outer side of the sealed portion is projected outward more than the sealed portion side inner surface position of the flange part of the slinger and a part of a seal lip part is formed to be brought into elastically slidable contact with the extended end face of the slinger.
