PROBLEM TO BE SOLVED: To provide a sealing device capable of holding grease stably between an auxiliary lip and a shaft surface.SOLUTION: A sealing device 100 which seals an annular gap between a shaft 200 and a housing 300 rotating relatively, includes: a main lip 22 slidable with respect to a surface of the shaft 200; and an auxiliary lip 23 provided slidably with respect to the surface of the shaft 200, and provided so as to be adjacent to an atmosphere side (A) with respect to the main lip 22. In the sealing device 100, grease G is filled in space between the main lip 22 and the auxiliary lip 23. A tip of the main lip 22 is configured so as to extend straight with respect to a circumferential direction, and a tip of the auxiliary lip 23 is configured so as to extend in a wavy manner with respect to the circumferential direction. |
