<P>PROBLEM TO BE SOLVED: To provide a bearing device for a wheel installed to a knuckle by a stable fitting force even in a rise of a temperature, and stably performing revolution speed detection or the like. <P>SOLUTION: The bearing device for the wheel comprises: inner rings 24A, 24B having rolling faces 28, 29 on outer diameter surfaces; an outer ring 25 having rolling faces 26, 27 on an inner diameter face; rolling elements 30 housed rollingly between an outer rolling faces 26, 27 of the outer ring 25 and inner rolling faces 28, 29 of the inner rings 24A, 24B. In the bearing device for a wheel, at least the outer ring 25 is molded by cold rolling, and an annular recess 51 is formed at the axially center of the outer diameter face 50 of the outer ring 25. A resin band 17 formed of heat-resistant synthetic resin is filled in the annular recess 51 of the outer ring 25. A sensor unit is disposed at the resin band 17. <P>COPYRIGHT: (C)2009,JPO&INPIT |
