Abstract
A rotary seal is used for a horizontal rotation axis or an inclined rotation axis, and has a slinger including a cylindrical portion and an outward flange portion, a core metal including a cylindrical portion and an inward flange portion, and a seal member including a base joined to the core metal and an axial lip brought into sliding contact with an axially inner surface of the outward flange portion. The rotary seal includes a lip wetting inhibitor located radially outward of the axial lip, in which a gap is provided between a tip end of the lip wetting inhibitor and the axially inner surface of the outward flange portion, and the tip end of the lip wetting inhibitor does not contact the axially inner surface even if the lip wetting inhibitor is applied with a water pressure and elastically deformed.
