PROBLEM TO BE SOLVED: To provide a technology which relates to a high strength boss member, prevents movement of the boss member relative to a hub part, and achieves weight reduction.SOLUTION: A motor cycle 10 includes a wheel 80 made of a light alloy. A wheel support mechanism 60 includes: a hub part 81 formed at a center part of a wheel 80; a boss member 90 configured to be press-fitted in the hub part 81; and an axle 62 inserted into the boss member 90. The boss member 90 is coupled to the axle 62 so as to restrict rotation and is made of the same kind of a light alloy having strength higher than that of the hub part 81.SELECTED DRAWING: Figure 2

    【課題】高強度なボス部材であって、ハブ部との相対移動を防止するとともに軽量化を図ることができる技術を提供することを課題とする。【解決手段】自動二輪車10は、軽合金で形成されたホイール80を備える。ホイール支持機構60は、ホイール80の中心部に形成されるハブ部81と、このハブ部81に圧入されるボス部材90と、このボス部材90に挿入される車軸62とを備える。ボス部材90は、車軸62に回転が規制されるように結合されるとともに、ハブ部81よりも高強度な同種の軽合金で形成されている【選択図】図2
