摘要： A sealing device includes a side lip contacting with a surface angled to the axis. To optimize the cross sectional shape of the side lip, T1/T3 is set to not less than 0.5 and less than 0.8 and L2/L1 is set to 0.2 to 0.4, where the thickness of the lip end (5c) of the side lip (5) is T1, the thickness of the lip base (5a) is T3, the length of the lip end (5c) is L1, and the length of the lip base (5a) is L2. Further, in a sealing device which includes a side lip (5) contacting with a surface angled to the axis over its contact width, the maximum value of the surface pressure in the side lip (5) is set at the most leading end (5d) of the lip.
