A bearing lubricating device includes: oiling means (14, 15) for supplying a predetermined amount of lubricating oil to a shoulder peripheral surface (3B) of a race ring (3) of a rolling bearing (1) located on a side of a raceway surface (3A) of said race ring (3) of said rolling bearing (1); and air jetting means (16, 19) for jetting air so as to transfer the lubricating oil on said shoulder peripheral surface (2A) toward an interior of said bearing (1), wherein said air jetting means (16, 19) has a receiving space (17) formed in a side member (11) disposed on a side of and adjacent to a nonrotating race ring of said bearing so as to receive air from an outside as well as an air jetting slit (16) communicating with said receiving space (17), said air jetting slit (16) having an annular shape concentric with said 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 said bearing. <IMAGE> |
