PURPOSE: Hub bearing sealing structure of a vehicle is provided to improve sealing efficiency, and to prevent inflow of foreign matters by increasing downward pressure with embedding a coil spring and a magnet in a seal. CONSTITUTION: A bracket(54) is connected to a knuckle to prevent inflow of foreign matters to a hub. A seal(56) is inserted to the bracket, and pressed in a sill of a driving shaft(50) to seal a hub bearing(52). Plural magnets(1) are mounted in the seal, and the position of the magnet is restricted by a coil spring(2). The hub is assembled with the knuckle in inserting the hub bearing, and the seal is installed between the sill of the driving shaft and the knuckle. The seal is contacted to the sill with magnets of the seal, and moved with pressing downward by the spring. Sealing efficiency between the seal and the sill of the driving shaft is improved, and the life span of the hub bearing is extended with preventing inflow of foreign matters.
