<p>The present invention relates to a connection structure for a hub and an out-lace of a vehicle capable of maintaining bond strength, noise prevention performance, and transmission performance and of facilitating a connection method while reducing an entire weight by changing the shape of the out-lace and a wheel bearing hub by including a separate coupling member formed to be suitable to couple the same. The connection structure comprises: an out-lace rotated by receiving a driving force of a vehicle power device; a hub connected to the out-lace to transmit the driving force by a female serration whereby a retainer ring groove is formed on one side of a central through-hole; a wheel bearing rotated to be connected to the outer surface of the hub and fixated to a vehicle body; a retainer ring inserted and fixated to the retainer ring groove of the hub; and a bolt inserted into the center of the retainer ring to connect the hub and the out-lace.</p> |
