To solve problems that, in a prior art, when attaching a wheel, when a wheel whose seat surface is a taper seat or a spherical seat is replaced with a wheel whose seat surface is a plane seat, the wheel cannot be attached by a same nut due to difference of a seat surface, therefore, processing for changing the seat surface of the wheel is required, such as exchange of a nut seat bushing, or a nut which matches a seat surface of a wheel has to be prepared newly, and using the nut, the wheel has to be attached.SOLUTION: An adaptor in the invention is held between a wheel whose seat surface at a wheel side is a plane seat, and a nut whose seat surface on a nut side is a taper seat or a spherical seat, and a spacer of a hub bolt part adjusts a gap amount between the wheel and the bolt, simultaneously, the plane seat of the wheel seat surface is converted into the taper seat or the spherical seat of the nut seat surface, so that, without exchange of the nut seat bushing, and processing of the wheel and the nut, a wheel can be attached by a nut having a different seat surface shape.SELECTED DRAWING: Figure 1

    【課題】 従来のホイールの取り付けに関しては、座面がテーパー座もしくは球面座のホイールから、平面座のホイールへ付け替える際には、座面の違いにより同じナットで取り付けることが出来ない。そのため、ナット座ブッシュの付け替えなど、ホイールの座面を変更する加工を行うか、取り付けようとするホイールの座面に合うナットを新たに用意し、そのナットを使って取り付ける必要があった。【解決手段】 ホイール側の座面が平面座となっているホイールと、ナット側の座面がテーパー座もしくは球面座となっているナットの間にこの発明であるアダプターをはさみ、ハブボルト部のスペーサーでホイールとボルト間の隙間の量を調整し、それと同時にホイール座面の平面座からナット座面のテーパー座もしくは球面座に変換することで、ナット座ブッシュの付け替えや、ホイールやナットの加工をせずに座面の形状が異なるナットでホイールを取り付けることが可能となる。【選択図】図1
