PROBLEM TO BE SOLVED: To easily perform the centering of a hub bolt and a wheel attachment hole which is formed at the hub bolt without being largely influenced by an individual difference such as a level of skill of a worker when performing the attachment work of a wheel.SOLUTION: An automobile wheel attachment auxiliary implement is used for attaching a wheel 30 to a hub 10 by screwing wheel nuts 35 into hub bolts 20 after fitting attachment holes 32 at four points of the wheel 30 to four pieces of the wheel bolts 20 which are arranged in circumferential directions at equal pitches. A withdrawal cylinder part 51 as a spacer for centering is arranged in a clearance between cylindrical internal peripheral faces 33 of the attachment holes 32 and external peripheral faces 21 of the hub bolts 20. An insertion hole of a rod-shaped member which can be used as a grip can be formed at a grip part 52 which extends to a cylinder part 51.
【課題】ホイールの取付け作業に際して、ハブボルトとハブボルトに嵌合されたホイールの取付け孔との芯出しを、作業者の熟練度合などの個人差による影響をそれほど受けることなく容易に行うことができるようにする。【解決手段】円周方向に等ピッチで配列された4本のハブボルト20に、ホイール30の4箇所の取付け孔32を嵌合した後に、ハブボルト20にホイールナット35をねじ込むことによってホイール30をハブ10に取り付けることに用いられる。取付け孔32の円筒状の内周面33とハブボルト20の外周面21との隙間に挿抜可能な芯出し用スペーサとしての円筒部51を備える。円筒部51に延設した把持部52に、把手として利用可能なロッド状部材の挿入孔を設けることが可能である。【選択図】図6
