Abstract
A sealing device used for a bearing includes an outer race, an inner race, and rotatable members. The inner race includes a flange that faces an edge face of the outer face. The sealing device includes a cylindrical portion, an extension portion, a first annular protrusion, and a second annular protrusion. The cylindrical portion is fixed to an inside of the outer race. The extension portion extends radially outward of an outer surface of the outer race from an end of the cylindrical portion. A part of the extension portion contacts the edge face of the outer face. The first protrusion extends toward the flange from an outer edge of the extension portion. The second protrusion extends toward the flange from a portion that is a part of the extension portion and is radically inward of the first protrusion.
