A rotary seal that includes: a slinger including a cylindrical portion and an outward flange portion extending radially outward from an axial end of the cylindrical portion; a core metal including a cylindrical portion and an inward flange portion extending radially inward from an axial end of the cylindrical portion; and a seal member including a base joined to the core metal and a seal lip including an axial lip that extends from the base and is brought into sliding contact with an axially inner surface of the outward flange portion, the rotary seal for being used in a state where the cylindrical portion of the slinger is attached to an inner ring of an automobile wheel bearing, the inner ring being a radially inner member, and the cylindrical portion of the core metal is attached to an outer ring of the automobile wheel bearing, the outer ring being a radially outer member, the rotary seal comprising a lip wetting inhibitor that is located radially outward of the axial lip and protrudes axially from the base or the inward flange portion toward the outward flange portion, wherein a first gap is provided between a tip end of the outward flange portion of the slinger and an outer circumferential seal portion that covers a tip end of the cylindrical portion of the core metal, or between an outer circumferential seal portion that covers a tip end of the cylindrical portion of the core metal and a wraparound portion of a magnetic encoder joined to the outward flange portion of the slinger, a second gap is provided between a tip end of the lip wetting inhibitor and the axially inner surface of the outward flange portion or between the tip end of the lip wetting inhibitor and the wraparound portion of the magnetic encoder joined to the outward flange portion, an angle (α) formed by an axial direction and a straight line in the end view of the cut portion is 40° or more and less than 90°, the straight line connecting a tip end of a radially outer circumferential surface of the lip wetting inhibitor and an outer circumferential edge of the axially inner surface of the outward flange portion to each other, the tip end of the lip wetting inhibitor does not contact the axially inner surface even when the lip wetting inhibitor is applied with a water pressure and elastically deformed, and a brim portion that protrudes radially outward is provided on a tip end portion of the radially outer circumferential surface of the lip wetting inhibitor. a slinger including a cylindrical portion and an outward flange portion extending radially outward from an axial end of the cylindrical portion; a core metal including a cylindrical portion and an inward flange portion extending radially inward from an axial end of the cylindrical portion; and a seal member including a base joined to the core metal and a seal lip including an axial lip that extends from the base and is brought into sliding contact with an axially inner surface of the outward flange portion, the rotary seal for being used in a state where the cylindrical portion of the slinger is attached to an inner ring of an automobile wheel bearing, the inner ring being a radially inner member, and the cylindrical portion of the core metal is attached to an outer ring of the automobile wheel bearing, the outer ring being a radially outer member, the rotary seal comprising a lip wetting inhibitor that is located radially outward of the axial lip and protrudes axially from the base or the inward flange portion toward the outward flange portion, wherein a first gap is provided between a tip end of the outward flange portion of the slinger and an outer circumferential seal portion that covers a tip end of the cylindrical portion of the core metal, or between an outer circumferential seal portion that covers a tip end of the cylindrical portion of the core metal and a wraparound portion of a magnetic encoder joined to the outward flange portion of the slinger, a second gap is provided between a tip end of the lip wetting inhibitor and the axially inner surface of the outward flange portion or between the tip end of the lip wetting inhibitor and the wraparound portion of the magnetic encoder joined to the outward flange portion, an angle (α) formed by an axial direction and a straight line in the end view of the cut portion is 40° or more and less than 90°, the straight line connecting a tip end of a radially outer circumferential surface of the lip wetting inhibitor and an outer circumferential edge of the axially inner surface of the outward flange portion to each other, the tip end of the lip wetting inhibitor does not contact the axially inner surface even when the lip wetting inhibitor is applied with a water pressure and elastically deformed, and a brim portion that protrudes radially outward is provided on a tip end portion of the radially outer circumferential surface of the lip wetting inhibitor.
