PROBLEM TO BE SOLVED: To maintain an excellent sealability with a simple structure. SOLUTION: In this seal structure, an inner spherical surface 2a of an outer race 2 is provided with a groove 4 for sealing having a predetermined interval from an edge of the inner spherical surface 2a, and a shield member 5 is fitted to the groove 4 for sealing thereby abutting on a spherical surface 3a of an inner race 3. By this constitution, the simple seal structure of a spherical slide bearing 1 is realized, and the shield member 5 fitted to the groove 4 for sealing is brought into close contact with the spherical surface 3a of the inner race 3, thereby maintaining the excellent sealability. |
