PROBLEM TO BE SOLVED: To provide a bearing device for an axle preventing the deformation of a second inside race part of a cylindrical second inside member, smoothly rolling balls, and causing little rattling. SOLUTION: A shaft 1 is integrally formed with a joint part, or a part of a constant velocity joint, and a first inside race part 3. A cylindrical flange shaft 4 is provided with the second inside race part 16 and a flange part 6, while an outer ring 5 is provided with a flange part 7 and an outside race part 17. A plurality of balls 10, 10 are arranged between the first/second inside race parts 3, 16 and the outside race part 17. The shaft 1 is formed with a screw part 8 in its outer circumference and the flange shaft 4 is formed with a screw part 9 in its inner circumference so that the shaft 1 and the flange shaft 4 are fixed by the threaded engagement between the screw parts 8, 9. |
