ABSTRACT:
The present invention provides a grease composition capable of effectively preventing a rolling surface of a bearing from having hydrogen brittleness-caused peeling, a grease-enclosed bearing in which the grease composition is enclosed, and a rotation-transmitting apparatus with a built-in one-way clutch in which the grease composition is enclosed at a sliding portion. The grease composition contains a base grease consisting of a base oil and a thickener; and an additive added to the base grease. The grease composition prevents a frictional wear surface of the sliding portion or a newly generated surface consisting of iron or the like exposed owing to wear from being peeled owing to hydrogen brittleness. The additive contains a bismuth-based additive or a magnesium-based additive. The bismuth-based additive consists of at least one of inorganic bismuth and organic bismuth not containing a sulfur component. The magnesium-based additive consists of at least one of inorganic magnesium and organic magnesium. The grease-enclosed bearing encloses the above-described grease composition.
