Recoil tyre-sealing part

The utility model relates to a recoil tyre-sealing part with a spoke of human power or motor vehicles. The recoil tyre-sealing part is in circular shape, the shape of the inner side is consistent with the shape of downward concave bottom of the external side of a wheel rim, the shape of the external side is consistent with the inner edge of a recoil tyre, and the center of the inner side is opened with a groove. The utility model makes up the insufficiency of a recoil tyre, the gap between the spoke and the wheel rim is effectively sealed, the recoil effect of the recoil tyre is enhanced, and the performance of the elasticity and the load can be improved.
