Abstract: To secure a load bearing capability along with a smooth supply and drainage of a lubricant oil into and from a rolling bearing assembly, a retainer and the rolling bearing assembly provided with such retainer are of a design in which the retainer (5) includes an annular wing portion (5a) and a plurality of pillars (5b) extending from circumferential locations of the annular wing portion (5a) and formed with a pocket (6) between the neighboring pillars (5b) for rollingly retaining rolling elements (4) of the rolling bearing assembly. The annular wing portion (5a) has an inner peripheral surface formed to define an inclined annular face (7). This inclined annular face (7) is deployed over a substantially entire width of the annular wing portion (5a) in an axial direction of the retainer (5) and is inclined to flare axially outwardly to have a diameter decreasing towards a mid-center portion of the retainer (5) in the axial direction.
