PROBLEM TO BE SOLVED: To confirm a mounting state of a sealing device mounted for preventing outflow of differential oil from a fitting part of a rolling bearing device and an axle tube, after assembly of the rolling bearing device, in a rear axle, and to reliably prevent outflow of differential oil.SOLUTION: On a fitting surface of an inner ring 33 of a rolling bearing device 30 and an axle tube 12, a sealing device 46 is mounted at an outermost position in an axial direction of a vehicle, and thereby a radial gap between an inner periphery 33c of the inner ring 33 and an outer periphery 14 of the axle tube 12 is sealed.SELECTED DRAWING: Figure 3
【課題】 リアアクスルにおいて、転がり軸受装置の組み立て後に、転がり軸受装置とアクスルチューブとの嵌め合い部からのデフオイルの流出を防止するために装着する密封装置の装着状態を確認できるようにしたうえで、デフオイルの流出を確実に防止する。【解決手段】 転がり軸受装置30の内輪33と、アクスルチューブ12との嵌め合い面において、軸方向の最も車両外側の位置に密封装置46を装着し、前記内輪33の内周33cと前記アクスルチューブ12の外周14との径方向のすきまを密封する。【選択図】 図3
