A mixing ratio of the epoxy compound to 100 parts by weight of the base grease is set to 0.05 to 10 parts by weight. The grease-enclosed bearing using the grease composition includes an inner ring () and an outer ring (); a plurality of rolling elements () disposed between the inner ring () and the outer ring (); and a sealing member () for covering openings () disposed at both axial ends of the inner ring () and the outer ring (). The grease composition () is enclosed on peripheries of the rolling elements ().
