Abstract

A flywheel damper support structure includes a rolling bearing (6) interposed between an engine-side mass (2) and a transmission-side mass (3) of the flywheel damper for supporting the masses. The rolling bearing (6) has a grease filled therein, which grease contain urea as a thickening agent. Inner and outer races (11, 12) of the rolling bearing (6) is made of steel as a raw material, contains a retained austenite in a quantity not greater than 8% and has a hardness not lower than HRC 60. The amount of the grease filled is chosen to be within the range of 40 to 50% of an inner space of the rolling bearing (6). The grease is of a kind prepared from a synthetic oil as a base oil and containing an aromatic urea used as the thickening agent. Seals (15) are made of a fluorine-contained rubber.
