A sealed rolling bearing includes an outer race and an inner race. A cylindrical portion provided at the outer portion of a sealing member is press-fitted into each end of the outer race. A cylindrical portion provided at the inner portion of a slinger is press-fitted onto each end of the inner race. The sealing member has at its inner peripheral portion first and second radial lips which are in elastic contact with the slinger to prevent entry of foreign matter into the bearing space. The slinger has an annular portion including an axially outwardly extending, outwardly bent portion provided at its outer peripheral portion. The outwardly bent portion has an outer periphery located inwardly of the outer end of the cylindrical portion of the sealing member. A small gap is defined between the outwardly bent portion and the inner surface of the cylindrical portion as a labyrinth.
