Abstract
A bearing assembly for a vehicle includes an inner race made integral with the wheel, and an outer race disposed outside and concentrically with the inner race with rolling members interposed therebetween. The inner race is adapted to rotate relative to the outer race. The bearing assembly further includes an annular member including a fixed portion fixedly fitted to the outer peripheral surface of the outer race, an extension extending continuously to the fixed portion and extending while surrounding the outer race to form a desired seal portion between itself and the outer race, and a pulser gear portion comprising a plurality of concave and convex portions formed on the extension and provided circumferentially at intervals, and a sensor is disposed in proximity to the pulser gear portion, whereby the number of rotations of the wheel can be detected.
