<p>The present invention relates to a wheel hub assembly of a drive rear axle apparatus for a vehicle, which improves driving efficiency and fuel efficiency by reducing the total weight as well as reducing production costs by reducing material costs and the number of assemblers by reducing the number of elements of the wheel hub assembly by integrating a retainer with an oil seal. Moreover, the present invention can improve durability determined by the size by eliminating the restriction of the size by removing the spatial restriction of a wheel bearing due to other elements. The present invention comprises: the wheel bearing installed on the outer circumferential face of an axle shaft; a hub installed on the outer circumferential face of the wheel bearing, and combined with the axle shaft by using a bolt; a retainer-integrated seal installed on the outer circumferential face of the axle shaft, wherein the retainer and the oil seal are integrated; a stopper preventing separation of the retainer-integrated seal; and an outer oil seal installed between the wheel bearing and the axle shaft, and preventing an oil leak.</p> |
