PROBLEM TO BE SOLVED: To provide a cage device for a rolling bearing that exhibits a prolonged service life even under high-speed rotation. SOLUTION: A cage 7 has, in its front face 12, two surfaces 14 and 15 axially offset from each other. The first surface 14 has tabs 16 and 17 projecting therefrom axially, and spreads in a plane forward of a radial plane passing the center of cells 13. The second surface 15 spreads in a plane practically passing the center of the cells 13. |
