<p>PROBLEM TO BE SOLVED: To obtain a structure which can prevent the generation of an impression on an inside outer ring raceway when an impact load is applied.SOLUTION: A fixed-side flange 17a is comprised of a pair of first flange elements 21, 21 and a pair of second flange elements 22. Buffer members 24, 24 are arranged at axial inside faces of both the first flange elements 21, 21, and lock holes 25 are formed at external peripheral faces of both the second flange elements 22. Then, in a state that both the second flange elements 22, 22 are arranged in a horizontal direction of a vehicle, connecting bolts 32 are inserted into both the lock holes 25 and both screw holes 31 of a knuckle 16a. As above, an outer ring 3a is supported so as to be turnable in a vertical direction with respect to the knuckle 16a, and both the buffer members 24, 24 are elastically compressed in axial directions between the axial inside faces of the first flange elements 21, 21 and a side face of the knuckle 16a.</p> |
