Such an anti-slip pattern is generally made in a form in which a plurality of concave grooves are processed in a predetermined pattern.

For example, the anti-slip pattern is formed by arranging a plurality of grooves 11 machined on the upper plate 10 shown in FIG. 1 at regular intervals. In addition, grooves formed by the lattice-shaped edges 21 and 31 protruding from the upper plates 20 and 30 of FIGS. 2 and 3 are arranged at regular intervals. Therefore, due to the interference between the protruding parts around the groove 11 and the groove 11 and the wheel, or the grid-shaped protruding rims 21 and 31 and the groove formed therewith and the wheel, the sliding of the vehicle is reduced. can be reduced.

However, as shown in the above example, most of the anti-slip patterns have a concave groove or a form that makes a groove with a grid-shaped convex edge (hereinafter, collectively referred to as a 'groove type'), and these groove types are more common with wheels than flat ones. It may be ineffective in preventing slippage due to a small contact area. In addition, the groove-shaped anti-skid pattern has a problem in that when it rains, water accumulates in the groove and does not drain, resulting in a partial water film phenomenon, which may become an element that prevents the vehicle from slipping.
