The present invention relates to a sealing cap, of which durability with respect to a load is improved and simultaneously, the sealing performance thereof is improved, and to a wheel bearing assembly using the same. A wheel bearing assembly according to one embodiment of the present invention comprises: a hub having an outer side in the axial direction coupled to a wheel and formed with a stepped portion on an inner side in the axial direction; an outer wheel encompassing the outer circumferential surface of the hub and coupled to a vehicle body; an inner wheel inserted into the stepped portion of the hub; connectors interposed between the hub and the outer wheel and between the inner wheel and the outer wheel; and a sealing cap arranged on the inside of the hub and coupled to the outer wheel so as to prevent the introduction of foreign materials into the inner side, in the radial direction, of the outer wheel, wherein the sealing cap and the outer wheel are coupled such that one surface of the sealing cap comes into contact with one surface of the outer wheel, the one surface of the outer wheel is formed with a protrusion, and the one surface of the sealing cap is formed with a groove on which the protrusion is secured. |
