PROBLEM TO BE SOLVED: To inhibit scratches of a seal member of a unit bearing.SOLUTION: A bearing structure 1 for a wheel includes: an axle 2; a hub 3; and a unit bearing 4. The unit bearing 4 includes: a first inner race 11 and a second inner race 12; an outer race 13; a first rolling element 14 and a second rolling element 15; a first seal member 16 which seals a space between the first inner race 11 and the outer race 13 at the vehicle width direction inner side of the first rolling element 14; a second seal member 17 which seals a space between the second inner race 12 and the outer race 13 at the vehicle width direction outer side of the second rolling element 15; a bearing nut 8 which fastens the first inner race 11 and the second inner race 12 to the shoulder part 6 side; and a washer 9 disposed between the second inner race 12 and the bearing nut 8. The washer 9 has an elongated hole 21 which exposes the second inner race 12.SELECTED DRAWING: Figure 3
