To realize a structure which can prevent foreign objects, such as moisture and dust, from penetrating into an engagement part between a joint side face spline and a hub side face spline from the radial inner side of the engagement part.SOLUTION: A seal member 5 is disposed at a portion, which is located at the axial outer side relative to an engagement part between a hub side face spline 14 and a joint side face spline 32, of a portion between a hub 7 and a coupling member 4 and has an interference in a radial direction.SELECTED DRAWING: Figure 1
【課題】水分や塵芥などの異物が、ジョイント側フェイススプラインとハブ側フェイススプラインとの係合部に、該係合部の径方向内側から侵入することを防止できる構造を実現する。【解決手段】シール部材5は、ハブ7と結合部材4との間部分のうち、ハブ側フェイススプライン14とジョイント側フェイススプライン32との係合部よりも軸方向外側に位置する部分に配置され、かつ、径方向の締め代を有する。【選択図】図1
