To provide an assembling structure of a tire wheel, a brake rotor and a hub which allows easy execution of both the rotation phase adjustment work of the brake rotor with respect to the hub using a positioning bolt, and the insertion work of the positioning bolt into a positioning penetration hole.SOLUTION: This assembling structure comprises: a hub 20; a brake rotor 30; a tire wheel; at least one positioning bolt 50 having a first shaft part 52 in which a first head part 51 and a first male screw part 53 are formed; and a plurality of position fixing bolts each having a second shaft part in which a second head part and a second male screw part are formed. When an elastic body 55 attached to the first shaft part 52 is gripped by the first head part 51 of the positioning bolt 50 and the hub 20 by the screwing of the first male screw part 53 into a positioning female screw hole 29 of the hub 20, the elastic body 55 is deformed so as to be expanded in outside diameter compared with the case that the elastic body is in a free state.SELECTED DRAWING: Figure 6
【課題】位置決め用ボルトを利用したブレーキロータのハブに対する回転位相調整作業及び位置決め用ボルトの位置決め用貫通孔への挿入作業を共に容易に実行できるタイヤホイール、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】ハブ20と、ブレーキロータ30と、タイヤホイールと、第1頭部51及び第1雄ねじ部53が形成された第1軸部52を有する少なくとも1つの位置決め用ボルト50と、第2頭部及び第2雄ねじ部が形成された第2軸部を有する複数の位置固定用ボルトと、を備え、第1雄ねじ部53がハブ20の位置決め用雌ねじ孔29に螺合することにより第1軸部52に装着された弾性体55が位置決め用ボルト50の第1頭部51とハブ20とによって挟まれたときに、弾性体55が自由状態にあるときと比べて外径を大きくするように変形する。【選択図】図6
