Abstract
The invention relates to an anti-skid structure between a body and a rim of a hollow foam wheel, and more particularly, to a hollow-shaped foam wheel body put around a rim. The wheel body includes two flanges that are thick and close to each other. Pluralities of retaining flakes are disposed apart on the surface of the rim covered by the wheel body, and pluralities of protrusions are disposed apart on the surface of the flanges corresponding to the wheel body. As the wheel body is tightly put around the rim, the protrusions and the retaining flakes block one another, avoiding the skid between the wheel body and the rim. Furthermore, the pressure on the surface of the wheel is conducted to the flanges leaning on each other through the sidewalls thereof, and is then balanced. Hence, the deformation of the wheel body is decreased. The wheel can carry more load and serve as an optimal buffer when employed.
