PROBLEM TO BE SOLVED: To extend the lifetime of a bearing by improving the sealing performance of a sealing member to prevent a foreign substance such as water, muddy water, and the like from intruding from a fitting surface. SOLUTION: A sealing member 6 includes a slinger 63 fitted onto the outer circumferential surface of an inner wheel member 3, and an annular member 8a is externally fitted on the shoulder on the vehicle center side in the axial direction of an inner roll member 32A. The annular member 8a includes an inner circumferential surface 8a1 for pressing the axial leading end of the slinger 63 in the inner diameter side as a result of press-fitting the slinger 63. The axial leading end of the slinger 63 contacts with the inner circumferential surface 8a1 of the annular member 8a. COPYRIGHT: (C)2011,JPO&INPIT
