A rolling bearing device includes a rolling bearing unit having rolling elements retained by an annular retainer and intervening between raceways of inner and outer rings, and a nozzle member provided proximate to the outer ring. The nozzle member is provided with an annular collar portion inserted in a bearing space delimited between the inner ring and the outer ring and having a nozzle hole. This collar portion has an outer diametric surface in the form of a retainer guide surface, and an inner diametric surface of the retainer is guided by this retainer guide surface.
