PROBLEM TO BE SOLVED: To prevent a stopper bolt from blocking rotation of an outer race.SOLUTION: The present invention includes a knuckle 2, a hub 3, a unit bearing 4, and a stopper bolt 5 screwed into a bolt hole 2c of the knuckle 2 to restrict a maximum cutting angle of the knuckle 2. The unit bearing 4 includes a first inner race 11 and a second inner race 12, an outer race 13, and a first rolling element 14 and a second rolling element 15. An inner race end surface 11a as an end surface of the first inner race 11, which is located adjacent to a kingpin 7 is positioned closer to the kingpin 7 than an outer race end surface 13a as an end surface of the outer race 13, which is located adjacent to the kingpin 7. The first inner race 11 is positioned at least to close a portion of the bolt hole 2c as viewed from the direction in which the stopper bolt 5 is screwed into the bolt hole 2c.SELECTED DRAWING: Figure 2

    【課題】ストッパボルトがアウタレースの回転を阻害するのを防止する。【解決手段】ナックル2と、ハブ3と、ユニットベアリング4と、ナックル2のボルト穴2cにねじ込まれてナックル2の最大切れ角を規制するするストッパボルト5とを備え、ユニットベアリング4は、第一インナレース11及び第二インナレース12と、アウタレース13と、第一転動体14及び第二転動体15と、を有し、第一インナレース11のキングピン7側の端面であるインナレース端面11aは、アウタレース13のキングピン7側の端面であるアウタレース端面13aよりも、キングピン7側に位置し、ボルト穴2cに対するストッパボルト5のねじ込み方向から見て、第一インナレース11は、ボルト穴2cの少なくとも一部を塞ぐ位置に位置する。【選択図】図2
