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

    【課題】ホイール交換時のホイールの脱落及び/又は部品の損傷を防止し、作業効率を向上することが可能なホイール取付構造を提供する。【解決手段】ハブ軸部21からフランジ部22よりも車体外側に突設する、略円筒形状を有するインロー部23を備えるホイールハブ20に対する取付構造である。インロー部23には、回転軸線90と平行な円筒外周面が形成され、インロー部23に圧入固定されインロー部23の端部から所定距離離間した位置に径方向外向きに突設する鍔部がある鍔付き部材70が備えられる。中心孔52の内周面であってホイール50のハブ取付面51a側にホイールの中心に向かって円環状突起部54が突設し、ハブボルト60を用いてホイール50をフランジ部22に固定している状態においては、嵌合部と円環状突起部54との間においてインロー嵌合し、ハブボルト60が取り外された状態においては、円環状突起部54が鍔部に係止される。【選択図】図1
