PROBLEM TO BE SOLVED: To provide a structure for assembling a tire wheel, a brake rotor and a hub, which enables a rotative force of the brake rotor to be received by a shank of a bolt for positional fixation when the brake rotor is rotated relative to the hub due to a decrease in axial force of the bolt for positional fixation.SOLUTION: Cross-sectional shapes of a positioning through-hole 35, a first shank, a position fixing through-hole 33 and a second shank are set so that a total value of circumferential dimensions centering a rotational central axis of a first clearance CL1 can be greater than a total value of circumferential dimensions of a second clearance CL2 formed between an inner peripheral surface of each position fixing through-hole 33 and an outer peripheral surface of the second shank of each position fixing bolt 60.SELECTED DRAWING: Figure 5
【課題】位置固定用ボルトの軸力の低下に起因してハブに対してブレーキロータが相対回転したときに、ブレーキロータの回転力を位置固定用ボルトの軸部によって受けることが可能なタイヤホイール、ブレーキロータ及びハブの組付構造を提供する。【解決手段】第1クリアランスCL1の回転中心軸を中心とする円周方向の寸法の合計値が、各位置固定用貫通孔33の内周面と各位置固定用ボルト60の第2軸部の外周面との間にそれぞれ形成された第2クリアランスCL2の円周方向の寸法の合計値より大きくなるように、位置決め用貫通孔35、第1軸部、位置固定用貫通孔33及び第2軸部の断面形状が設定された。【選択図】図5
