<P>PROBLEM TO BE SOLVED: To provide a wind resistant color cone capable of solving such a problem that a color cone used for a field or the like of road work is easy to fall down in the case of a strong wind due to its conical shape, a weight is attached to a pedestal as the conventional technology for coping with the problem, projected stripes are made in the surface of the cone section to lower air resistance and that none of countermeasures can increase wind resistant performance according to wind velocity. <P>SOLUTION: Low repulsion resilient bodies 3a and 3b are mounted to the bottom section of the pedestal 2 of the color cone 1, and a plurality of chuck valves 4a and 4b (favorably more than four pieces) opened to the outside are mounted on the side of the cone section at regular intervals. <P>COPYRIGHT: (C)2007,JPO&INPIT |
