To realize a structure capable of preventing relative displacement of a slinger to a hub, while preventing galling and undesired deformation from occurring in the slinger, when the slinger is externally fitted to the hub.SOLUTION: An inner peripheral surface of a first seal member 30 coupled and fixed to a cylindrical part 32 of a slinger body 29 is externally fitted to a cylindrical surface part 15, and an axial outside surface of a second seal member 31 coupled and fixed to an axial outside surface (of an outer diameter side flat plate part 36) of an upright plate part 33 abuts against an axial inside surface (flat surface part 14) of a rotary flange 10.SELECTED DRAWING: Figure 2
【課題】スリンガをハブに外嵌する際に、前記スリンガにかじりや好ましくない変形が生じることを防止しつつ、前記ハブに対する前記スリンガの相対変位を防止することができる構造を実現する。【解決手段】スリンガ本体29の筒状部32に結合固定された第1シール材30の内周面を円筒面部15に外嵌し、かつ、立板部33(の外径側平板部36)の軸方向外側面に結合固定された第2シール材31の軸方向外側面を、回転フランジ10の軸方向内側面(平坦面部14)に突き当てる。【選択図】図2
