PROBLEM TO BE SOLVED: To provide a rolling bearing device configured so that foreign matter hardly intrudes into a part of a rolling bearing. SOLUTION: In a sealing member 6 which seals a vehicle inner-side opening of a hub unit 100 that is one example of the rolling bearing device, a top end portion of a raised wall part 32 of a slinger 24 is bent toward a seal member 23 along an axial direction A to form a first bent part 33. Further, a top end portion of the first bent part 33 is bent to the opposite side along the axial direction A to form a second bent part 34, and a top end portion of the second bent part is bent outwardly in the radial direction R to form a third bent part 35. Crank-shaped labyrinth parts 37 and 38 are formed between the outer surfaces of the second and third bent parts 34 and 35 and an inner circumferential surface 26a of a rubber seal part 26 of the seal member 23.
