Summary:To provide a sealing device which can exert excellent sealing persistence on a seal surface.SOLUTION: A sealing device includes a first seal member and a second member which rotate relatively with each other. At least on one of a seal surface of the first seal member and a seal surface of the second seal member, a polymer brush layer is provided. Each dry film thickness of the polymer brush layer is 0-10000nm, and the difference between each dry film thickness is equal to or greater than 100nm.SELECTED DRAWING: Figure 1 【課題】シール面において優れた密封持続性を発揮し得る密封装置を提供する。【解決手段】本発明の密封装置は、互いに相対回転する第1シール部材及び第2シール部材を備える。第1シール部材のシール面及び第2シール部材のシール面の少なくとも一方にポリマーブラシ層が設けられている。ポリマーブラシ層の各乾燥膜厚が0〜10000nmであり、各乾燥膜厚の差が100nm以上である。【選択図】図1
