<P>PROBLEM TO BE SOLVED: To provide a bearing device for a wheel capable of preventing an inner ring at an outboard side which easily causes creeps without increasing its weight and size and capable of avoiding shortening life of a bearing. <P>SOLUTION: The bearing device for the wheel consists of a hub 1 and the bearing 2 for the wheel. The bearing 2 for the wheel has two inner rings 3A, 3B respectively press-fit to an outer circumference of a shaft part 1a of the hub 1 side by side in a shaft direction and double row outer rings 4. An inner ring width A' at the outboard side is wider than an inner ring width B' at an inboard side. <P>COPYRIGHT: (C)2008,JPO&INPIT |
