PROBLEM TO BE SOLVED: To hardly cause deterioration of a sealing material, keep good sealing performance for long time, and improve reliability and durability even when a rolling bearing for a flywheel damper filled with grease containing urea compound is used at a high temperature. SOLUTION: This rolling bearing for a flywheel damper includes: an inner ring; an outer ring; a plurality of rolling elements interposed between the inner ring and the outer ring; and sealing materials provided on opening parts at both ends in the axial direction of the inner ring and the outer ring to seal the urea grease in the periphery of the rolling elements. The sealing material for sealing the grease at least includes a rubber formed body coming into contact with the grease. The rubber formed body is a formed body of vulcanizable fluororubber composition made of a copolymer containing tetrafluoroethylene, propylene, and a crosslinkable monomer consisting of unsaturated hydrocarbon having two to four carbon atoms, in which a part of hydrogen atoms is substituted with fluorine atoms, and this flywheel damper support structure uses the rolling bearing for the flywheel damper.
