A bearing lubricating device includes: an oiling mechanism for supplying a predetermined amount of lubricating oil to a shoulder peripheral surface of a race ring of a rolling bearing located on a side of a raceway surface of the race ring of the rolling bearing; and air jetting mechanism for jetting air so as to transfer the lubricating oil on the shoulder peripheral surface toward an interior of the bearing, wherein the air jetting mechanism has a receiving space formed in a side member disposed on a side of and adjacent to a nonrotating race ring of the bearing so as to receive air from an outside as well as an air jetting slit communicating with the receiving space, the air jetting slit having an annular shape concentric with the race ring and substantially continuous in a circumferential direction and being formed to be open in such a manner as to be oriented toward the interior of the bearing.
