A sealing device (18) seals an annular space between a first member (19) and a second member (20) that relatively rotate with respect to each other at a boundary portion between an inside and outside of a rolling bearing (10). The sealing device (18) includes a seal member (23) that is connected to one of the first member (19) and the second member (20) and that has a first seal lip (36) and a second seal lip (37) and a first sliding surface (24A) and a second sliding surface (24B) that are provided for the other one of the first member (19) and the second member (20) and over which the seal lips (36, 37) slide. A second contact pressure (PO) of the second seal lip (37) against the second sliding surface (24B) is higher than a first contact pressure (PI) of the first seal lip (36) against the first sliding surface (24A). |
