PROBLEM TO BE SOLVED: To provide a seal structure which enables improvement of a foreign object entry prevention function while avoiding increase of torque resistance generated therein.SOLUTION: A seal structure 1 includes: a seal device 10 attached to an outer ring 51 of a hub bearing 50; an annular groove part 30 formed in the outer ring 51 and recessed inward; and a slinger 20 attached to a hub ring 55. The seal device 10 includes a reinforcement ring 12 and an elastic body part 11. The slinger 20 has an annular refracting part 20e projecting inward, and the refracting part 20e enters the groove part 30 to form a labyrinth seal.SELECTED DRAWING: Figure 1

    【課題】発生するトルク抵抗の増大を回避しつつ、異物の侵入防止機能を向上させることができる密封構造を提供する。【解決手段】密封構造1は、ハブベアリング50の外輪51に取り付けられる密封装置10と、外輪51に形成される内側に向かって窪む環状の溝部30と、ハブ輪55に取り付けられるスリンガ20とを備える。密封装置10は、補強環12と弾性体部11とを備える。スリンガ20は、内側に向かって突出する環状の屈折部20eを有しており、屈折部20eは、溝部30の内部に進入してラビリンスシールを形成している。【選択図】 図1
