1. A constant velocity joint for a vehicle, the constant velocity joint comprising:
a hub housing combined with the constant velocity joint in the hub housing;
a bearing assembly including an inner race fitted on an outer surface of the hub housing, an outer race spaced a predetermined distance apart from the inner race and fitted on a knuckle, and a power transmission member disposed between the inner race and the outer race; and
a boot having a band seat that is positioned on the inner race of the bearing assembly, the boot having a fixing band fixed on a top of the boot and the boot being coupled to the inner race by the fixing band, wherein the boot includes a boot lip that is formed at one end or both ends of the band seat and protrudes toward the knuckle;
wherein the boot and the knuckle are spaced apart from each other by a gap;
wherein the bearing assembly and the knuckle are spaced apart from each other by the gap, and
wherein, in the gap, the boot lip is formed to protrude towards the knuckle from at least one of an outer end of the band seat which faces an outside of a vehicle or an inner end of the band seat which faces an inside of the vehicle, thereby preventing foreign substances from penetrating into the bearing assembly by bending a movement path of the foreign substances entering between the boot and the knuckle.
