埋没し、ネツト本体に固定する。 The shape and dimensions of the recessed groove should be the same as the flange of the spike pin to be used, and should be set so that it is just perfectly buried.
On the other hand, a through hole is provided in the center of the bottom surface of the recessed groove so that the shank portion of the spike pin to be used is tightly inserted therethrough. In other words, the recessed groove and the through hole form a step-like through hole all around the circumference with a structure and dimensions suitable for the main body (flange part and shank part) of the spike pin. The spike pin is fixed to the net main body by being buried in such a way that the tip part protruding from the flange surface thereof protrudes from the upper surface of the ground plane.

である。[Function] As mentioned above, in the tire slip prevention device of the present invention, only the tip portion of the spike pin protrudes from the ground surface of the net body, and not only the shank portion but also the flange portion is buried in the net body. As a result, damage and wear on the flange of the spike pin are significantly reduced, and in particular, the edge of the flange surface, which has been a problem in the past, wears out and deforms into a blade shape.
This prevents the undesirable effect of cutting the rubber portion around the flange portion and hastening its damage, and significantly reduces damage and wear to the surrounding rubber portion.

Not only the shank part but also the flange part of the spike pin is buried there, and only the tip part protrudes toward the ground surface, so the spike pin will not shift or move when driving on icy roads or other road surfaces. In addition, the tip of the spike pin firmly bites into the icy surface, and the spike pin does not tilt even when it bites in. Furthermore, it is effective against slipping not only on snowy roads but also on icy roads. can be fully and reliably and effectively demonstrated,
In addition, it is possible to prevent damage and wear on the spike pin itself, especially around the edges of the flange, which conventionally tend to occur while driving on icy roads, etc., as well as prevent damage and wear on the rubber covering band around the flange of the spike pin. This is a tire anti-slip device that is extremely advantageous in practice, as it can significantly reduce wear and, in turn, bring the actual life of the tire anti-slip device itself much closer to its original service life.
