ROLLING BEARING

PROBLEM TO BE SOLVED: To provide a rolling bearing in which in cases where grease containing an urea compound is encapsulated in a rolling bearing, an elastic body of a hermetically-sealed plate acting as a sealing member is less deteriorated even when a bearing ambient temperature becomes high and thereby good seal performance is allowed to hold over the long term, thus realizing excellence in reliability and endurance. SOLUTION: There is provided the rolling bearing used for a supporting member for supporting a drive shaft in a freely rotatable manner at a vehicle body side. The rolling bearing is equipped with an outer race and inner race, a plurality of rolling elements intervened between the inner and outer races, grease containing the urea compound encapsulated in a periphery of the rolling elements, and a sealing member provided at openings of both ends in an axial direction of the inner and outer races to encapsulate the grease. The sealing member includes a molded rubber body in contact with at least the grease. The molded rubber body is formed of a fluorocarbon-rubber composite that contains tetrafluoroethylene, propylene and cross-linking monomers consisting of unsaturated hydrocarbon with the number of carbons 2 to 4 created by replacing part of hydrogen atoms with fluorine atoms and can be vulcanized.
