PURPOSE: A rear axle sealing structure is provided to improve the durability of a hub bearing by improving the sealability of a rear axle and to enable the stable operation of a wheel speed sensor. CONSTITUTION: A rear axle sealing structure comprises a mounting member(100), a rear hub bearing(200), a hub cap(300), a wheel speed sensor(400), and first and second sealing rings(500,600). The mounting member is fixed to a rear axle(10). The rear hub bearing is coupled to the outer surface of a coupling hole of the mounting member. The wheel speed sensor is coupled to one side of the mounting member to be adjacent to a sensor wheel of the rear hub bearing. The first sealing ring seals the gap between the mounting member and the hub cap. The second sealing ring seals the gap between the hub cap and the wheel speed sensor. |
