摘要：
A sealing device with a side lip contacting with a surface angled relative to its axis in which the cross sectional shape of the side lip is optimized. Where the thickness of the tip end (5c) of the side lip (5) is T1, the thickness of the base (5a) of the lip (5) is T3, the length of the tip end (5c) is L1, and the length of the base (5a) is L2, T1/T3 is set to be not less than 0.7 and less than 0.8 and L2/L1 is set to be not less than 0.5 and less than 0.6.
