HUB- INTEGRATED-TYPE CONSTANT-VELOCITY JOINT DEVICE

A hub-integrated-type constant-velocity joint device in which one hub housing () functions as both an outer race of a constant velocity joint and a wheel hub combining a disc () of a wheel and a knuckle (). In this configuration, a boot sealing portion () integrally formed at a boot () is inserted in a gap () between an inner race () and an outer race () of a bearing (), thereby functioning as an inner seal closing up the gap between the inner race () and the outer race ().
