PURPOSE: A seal for a wheel bearing of a vehicle is provided to improve the fuel efficiency of the vehicle by reducing the drag torque of a wheel bearing while preventing the penetration of external foreign substances. CONSTITUTION: A seal(100) comprises an outer member(200), an inner member(400), and a seal member(300). The seal member is installed in between the outer and inner members. The seal member comprises a plurality of seal ribs(311-314). The seal ribs are partially or entirely adhered to the inner circumference of the inner member by being hindered. The hindered seal ribs are asymmetrically shaped with a higher hindrance rate on the top than the bottom. The cross-section of the outer member has an L-shape. The cross-section of the inner member has a U-shape. [Reference numerals] (AA) Top of vehicle; (BB) Bottom of vehicle |
