Abstract:
PROBLEM TO BE SOLVED: To provide a wheel mounting structure capable of preventing a wheel from failing off and/or preventing components from being damaged during wheel replacement to enable improvement of work efficiency.SOLUTION: A mounting structure of a wheel hub 20 is provided. The wheel hub 20 includes a spigot joint part 23 having a substantial cylindrical shape and protruding from a hub axle part 21 to a vehicle-body outer side with respect to a flange part 22. The spigot joint part 23 has a cylindrical outer peripheral surface parallel to a rotation axis 90 and includes a collared member 70 having a collar part which is press-fitted into and fixed to the spigot joint part 23 and which protrudes outward in a radial direction at a position away from an end part of the spigot joint part 23 by a predetermined distance. On an inner peripheral surface of a center hole 52 and at a hub mounting surface 51a side of the wheel 50, an annular protruding part 54 is protruded toward the center of the wheel. In a state where the wheel 50 is fixed to the flange part 22 by using hub bolts 60, spigot-fitting is applied between a fitting part and the annular protruding part 54. In a state where the hub bolts 60 are removed, the annular protruding part 54 is locked by the collar part.SELECTED DRAWING: Figure 1
