PROBLEM TO BE SOLVED: To provide a bearing device for a wheel capable of facilitating preload control and applying a preload amount with no variations even when a bearing seal is attached. SOLUTION: The bearing device for a wheel, rotatably supporting the wheel to a vehicle body, comprises an outer member 1, an inner member 2 and a rolling body 3 interposed between the outer member 1 and the inner member 2. The outer member 1 has a vehicle installation flange 1a on an outer periphery, and double row rolling surfaces 6, 7 are formed on its inner-periphery surface. Rolling surfaces 8, 9 facing the rolling surfaces 6, 7 of the outer member 1 are formed on the inner member 2. The plurality of rolling body 3 is interposed between the rolling surfaces between the members 1, 2. A sensor 4 for detecting the pre-load quantity of the bearing is arranged either at the outer member 1 or the inner member 2. COPYRIGHT: (C)2005,JPO&NCIPI
