PROBLEM TO BE SOLVED: To provide a sealing device having high muddy water resistance.SOLUTION: There is provided an annular sealing device 10 which is fixed to an outside member 3 between an inside member 2 relatively rotating with a center axial C as a center and the outside member 3 which are located so as to coincide with the center axial C, and has a side lip 12g over an entire periphery. In the sealing device 10, the inside member 2 comprises a flange part 2c protruding to the outside of a radial direction of the center axis C, and a side face 2e at a side opposing the outside member 3 of the flange part 2c comprises a linear part 2f which extends to a direction separating from the center axial C when viewed from a cross section, and a step part 2g extending to a direction separating from the outside member 3 further from the linear part 2f. A tip 12k of the side lip 12g extends up to a position which opposes the step part 2g.SELECTED DRAWING: Figure 2
【課題】高い耐泥水性を有する密封装置を提供する。【解決手段】中心軸Cを同一とするように位置せしめられて該中心軸Cを中心に相対的に回転する内側部材2と外側部材3の間に、該外側部材3に固定されて設けられ、全周にわたってサイドリップ12gを備える環状の密封装置10であって、前記内側部材2は、前記中心軸Cの径方向外方へ突出するフランジ部2cを備え、該フランジ部2cの前記外側部材3に対向する側の側面2eは、断面視したときに、前記中心軸Cから離間する方向に延びる直線部2fと、該直線部2fから更に、前記外側部材3から離間する方向に延びる段部2gとを備え、前記サイドリップ12gの先端12kは、前記段部2gに対向する位置まで延びている、密封装置10を提供する。【選択図】図2
