Abstract
A joint structure of a wheel bearing comprises a bearing cover and a pivotal casing. The bearing cover has an outer edge being installed with a plurality of upper sheets which expand outwards; and between two upper sheets are formed with a downward extending lower sheet. The pivotal casing has a top being formed with a yoke; and the yoke is installed with a through hole with respect to the lower sheet. The lower sheet passes through the respective through hole. Thereby, the lower sheet penetrates through the respective through hole and the bottom of the upper sheet resists against the top of the yoke, then the lower sheet bends outwards to press the bottom of the yoke. Therefore, the bearing cover is steadily fixed to the yoke of the pivotal casing. No extra welding is necessary for enhancing the structure.
