Abstract
A sealing device is disposed between an inner member and an outer member of a rolling bearing that rotate relative to each other, and that acts to seal a gap between the inner member and the outer member. The sealing device includes an annular rigid part that is to be fixed to an inside of a hole of the outer member, the rigid part made from a rigid material; and an elastic part fixed to the rigid part, the elastic part made from an elastic material. The elastic part includes a seal lip having a truncated cone ring shape that is to be in slidable contact with the inner member or a member fixed to the inner member. Multiple bumps are formed on an inner peripheral surface of the seal lip, and are to be always in slidable contact with the inner member or the member fixed to the inner member. Clearances are provided between the seal lip and the inner member or the member fixed to the inner member in vicinities of the bumps.
