    • PROBLEM TO BE SOLVED: To provide a new sealing structure by which muddy water or the like from the outside hardly reaches a sliding contact part between a lip of a sealing member fitted to a bearing and a metal ring, and the life of the bearing can be improved.SOLUTION: A sealing structure 1 includes an inside member 20 and an outside member 30 which undergo relative rotation about an axis, and a sealing member 10 which is fitted to the outside member so as to seal an annular gap S between the inside member and the outside member. The inside member has a flange part 21 which continuously increases in diameter, and a rustproof metal ring 25 mates with the inside member including a base part 22 of the flange part. The sealing member has at least one lip 16 (17, 18) in sliding contact with the metal ring. A folded part 29 which is projected opposite to the flange part in the axial direction is provided on the outside diameter side of the metal ring. The outside member is provided with an extension part 35 which is further located on the outer side in the radial direction than the folded part of the metal ring, and extends to the flange part side.
    • 要解决的问题:为了提供一种新的密封结构,通过该密封结构,来自外部的泥水等几乎不能到达装配到轴承的密封构件的唇缘和金属环之间的滑动接触部分,并且轴承的寿命 解决方案:密封结构1包括内部构件20和围绕轴线相对旋转的外部构件30以及密封构件10,该密封构件10装配到外部构件以密封内部的环形间隙S 会员和外部会员。 内侧部件具有直径连续增加的凸缘部21,防锈金属环25与包括凸缘部的基部22的内侧部件配合。 密封件具有与金属环滑动接触的至少一个唇缘16(17,18)。 在金属环的外径侧设置有沿轴向与凸缘部相对地突出的折叠部29。 外部构件设置有延伸部35,其延伸到凸缘部侧,该延伸部35位于比金属环的折叠部的径向外侧的外侧。
