PROBLEM TO BE SOLVED: To provide a rolling bearing incorporating a sealing device which can be applied to a bearing having a small dimensional difference between the outer diameter of a rotary body and the outer diameter of an outer race without deteriorating the effect of preventing penetration of liquid. SOLUTION: A sealing device incorporated in the impeller side of a rolling bearing, is composed of a seal ring 5 and a flinger 6, the seal ring 5 comprising a reinforcing ring 5e, and an elastic member composed of four parts, that is, a first sublip part, a main lip part 5a, a second sublip part 5c located outside of the main lip part 5a and a fitting part, and the flinger 6 comprising a first cylindrical part 6a and a second cylindrical part 6b. Further, a rotary body 2 is composed of a large diameter part 2a and a small diameter part 2b, the main lip part 5a making slide contact with the large diameter part and the first cylindrical part 6a being fitted on the small diameter part 2b. |
