Provided is a sealing device equipped with a seal lip and a dust lip, and having a structure that makes it difficult for the dust lip to deform by swelling, thereby being less prone to sealability losses, even when anti-static measures (i.e., measures against radio noise) are implemented. The sealing device is provided with a seal lip, which seals in such a manner that foreign matter outside a machine does not penetrate into the machine, and a dust lip that makes it difficult for foreign matter to reach the seal lip, and is characterized in that the seal lip is formed by a conductive rubber material, and the dust lip is formed by a material having lower conductivity than the seal lip. The seal lip comprises a material obtained by blending 3 to 50 parts by weight of a conductive carbon with 100 parts by weight of rubber. The dust lip comprises a material obtained by blending 1 part by weight or less of a conductive carbon with 100 parts by weight of rubber. |
