    摘要： There is provided a rotary seal having uneven surfaces formed on sliding contact surfaces of a slinger with which seal lip portions of a seal member come in contact, in which wear of the seal lip portions is reduced, resulting in increased reliability. The rotary seal (1) includes: a core metal (3); the seal member (4) having a base portion (4A) joined to the core metal (3) and the seal lip portions (4B, 4C, and 4D); and the slinger (2) having the sliding contact surfaces (A and B) with which the seal lip portions (4B, 4C, and 4D) come in contact, in which each of the sliding contact surfaces (A and B) is in such a surface condition that an arithmetic average roughness Ra satisfies 0.3 µm ≤ Ra ≤ 1.0 µm, a skewness of roughness curve Rsk satisfies Rsk ≤ -1, and an average length of roughness curve element RSm satisfies 100 µm ≤ RSm, Ra, Rsk, and RSm defined by JIS B 0601:2013.
