PROBLEM TO BE SOLVED: To provide a cone for a road which is easy in handling at the time of transportation or arrangement. SOLUTION: The cone for the road is made of a flexible material having airtightness, and formed of a conical side wall sheet 19 capable of storing and filling gas 18, and a weighting section 14 connected to a lower portion of the side wall sheet 19, and capable of housing weighting materials 25a, 25b in a detachable manner. When the cone is in use, the weighting materials 25a, 25b are housed in the weighting section 14 by using a fastener 23 attached to a bottom sheet 22 constituting the weighting section, and then the fastener 23 is closed. In this state, by filling the gas 18 in the side wall sheet 19 via a plug 17, a cone body 13 is changed to a desired shape, and the cone for the road is completely formed. At the time of transportation, the gas 18 is discharged and the weighting materials 25a, 25b are removed, whereby the cone body 13 is flattened. COPYRIGHT: (C)2005,JPO&NCIPI
