A grease composition which can effectively prevent the flaking on, e.g., rolling/sliding surfaces mainly caused by hydrogen embrittlement; a prelubricated bearing containing the grease composition enclosed therein; and a rotation-transmitting apparatus of the built-in one-way clutch type which contains the grease composition enclosed in the sliding part. The grease composition is obtained by incorporating an additive into a base grease comprising a base oil and a thickener. The grease composition can prevent hydrogen embrittlement and resultant flaking from occurring on the frictional/wearingsurfaces of a sliding part or on a ferrous metal surface newly exposed by wearing. The additive comprises a bismuth additive or a magnesium additive, the bismuth additive being at least one member selected among inorganic bismuth compounds and organobismuth compounds containing no sulfur ingredient and the magnesium additive being at least one member selected among inorganic magnesium compounds and organomagnesium compounds.
