PROBLEM TO BE SOLVED: To attain a structure for sufficiently securing seal performance between a hub body and a slinger even when interference of a seal member for a slinger to an inside surface of a rotation side flange is reduced.SOLUTION: A seal member 15a for a slinger is provided with: a gasket part 36 fixed to an outside surface of a side plate part 17a of the slinger 13a; and eaves 35 arranged more outward in a radial direction from the gasket part 36. The gasket part 36 is elastically brought into contact with a more inside part in the radial direction from a step part 24 of the inside surface of a rotation side flange 9a. In addition, the tip part of the eaves 35 is made to closely face a more outside part in the radial direction from the step part 24 of the inside surface of the rotation side flange 9a, and the tip part of the eaves 35 and the step part 24 are superposed on each other in the radial direction. The above problem is solved by adopting such the structure. |
