    Abstract: To provide a wheel support bearing assembly having a capability of detecting the number of revolutions of a wheel, having no risk of breaking of wire outside a vehicle body, capable of reducing the weight and cost of an automotive vehicle. This wheel support bearing assembly for rotatably supporting a wheel 13 relative to a vehicle body structure 12 includes an outer member 1 having its inner periphery formed with plural rows of raceways 6 and 7, an inner member 2 having raceways 8 and 9 confronting respectively to the raceways 6 and 7, and rows of rolling elements 3 accommodated respectively between the raceways. An electric generator 4 for generating an electric power as one of the outer and inner members 1 and 2 rotates relative to the other of the outer and inner members 1 and 2. A signal indicative of the number of revolutions of the wheel 13 outputted from the electric generator 4 is transmitted wireless by mean of a wireless transmitting means 5A.

    Abstract: In a bearing apparatus for a wheel in which a hub, a constant velocity universal joint and double rows of bearings are united and one inner raceway of double rows of inner raceways, of the double rows of bearings is integrally formed with an outer joint member of the constant velocity universal joint, a stem portion of the outer joint member is fitted to the hub, an unevenness portion is formed on an inner peripheral surface of the hub or an outer peripheral surface of the stem portion or both thereof, and the hub and the outer joint member are plastically connected by expanding the hollow stem portion from an inner diameter side to an outer diameter side by caulking. Accordingly, the fitted portions of the hub and the outer joint member are prevented from being loosened.
