<p>PROBLEM TO BE SOLVED: To provide an automobile hub unit 1a with sufficient durability by surely preventing an inner ring 3a from rotating about a hub body 2 and preventing the wearing out of a fitting section of the hub body 2 and the inner ring 3a. SOLUTION: An outer end surface 20 of the inner ring 3a is positioned axially outside the intersection of extensionsα,βof generating lines on first and second outer ring races 14, 15 formed in the inner peripheral surface of an outer ring 4. Fitting strength of the hub body 2 and the inner ring 3a is thereby increased enough to meet the needs.</p> |
