PROBLEM TO BE SOLVED: To provide a sealing device for a bearing for an axle shaft capable of maintaining a good sealing condition by suppressing heat generation by a non-contact sealing structure. SOLUTION: A first partition member 3 is fitted and fixed in an inner diameter side of a seal case 22 of which one end is fixed on an outer ring 32a of the bearing 32 via a first annular member 2. A second partition member 5 is fitted and fixed on the axle shaft 31 via a slinger 33 and a second annular member 4. Lubricant 6 filled in a minute gap S1 between opposed surfaces of the first and the second partition member 3, 5 is retained in an rough surface 8a formed on the opposed surface of the second partition member 5.
