To realize a structure capable of sufficiently securing sealability for a long period.SOLUTION: A rotary opposite surface 40 provided on a slinger 26 and a stationary opposite surface 39 provided on a labyrinth slip 36 are made closely face each other, thereby forming a labyrinth seal 41 between the rotary opposite surface 40 and the stationary opposite surface 39. The labyrinth slip 36 elastically deforms in a direction in which the distance between the stationary opposite surface 39 and the rotary opposite surface 40 decreases with the rotation of a hub.SELECTED DRAWING: Figure 2
【課題】密封性を長期間にわたり十分確保することができる構造を実現する。【解決手段】スリンガ26に備えられた回転対向面40と、ラビリンスリップ36に備えられた固定対向面39とを近接対向させることにより、回転対向面40と固定対向面39との間に、ラビリンスシール41を構成する。ラビリンスリップ36は、ハブの回転に伴って、固定対向面39と回転対向面40との間隔を小さく方向に弾性変形する。【選択図】図2
