To provide a rolling bearing device which hardly creeps even if contained in a housing made from a material such as aluminum alloys with a greater coefficient of thermal expansion than ferrous materials, while making its manufacturing and assembling costs lower than those for conventional bearing devices designed to prevent creeping.

An energizing means 3 is interposed between the rear inner wall surface 22a of a housing along the direction of insertion of a bearing and one end face 12b of an outer ring 12 of the rolling bearing 1, and a snap ring is provided for resisting pressure produced by the energizing means so as to prevent the axial movement of the outer ring 12. With the outer ring of the rolling bearing 1 pressed by the energizing means 3 from each side, the rolling bearing device is incorporated into the housing 2 whereby rotation relative to the housing is prevented by its frictional force to prevent creeping. A standard rolling bearing 1 is usable, and during assembly only the snap ring 4 is mounted while the energizing means 3 applies a preload, thereby reducing the costs of manufacture and assembly.
