A gap sealing apparatus of a rolling fastening body includes an outer fastening sealing cover(2), a middle connection sealing member(3), an inner fastening retainer(4), and a washer. A fastening section(14) is formed on the inner peripheral surface of an inner fastening pipe body(11). A rib(17) is inclined outward at a corner where a sealing cover body and the inner fastening pipe body are connected. The middle connection sealing member interrupts a space between the outer fastening sealing cover and the inner fastening retainer. The inner fastening retainer interrupts a space between the outer fastening body and the middle connection sealing member. The washer is connected to the rear surface of the middle connection sealing member and is closely connected to the rib of the outer fastening sealing cover. |
