PROBLEM TO BE SOLVED: To provide a cone marker with rotors, the marker that can be moved easily even if two or more cone markers are stacked by mounting a base frame with casters in the lower part of an existing cone marker.SOLUTION: A cone marker includes a base plate and a conic protrusion projected upward from a predetermined position of an upper surface of the base plate. The cone marker with rotors is provided with at least one rotor in at least one side surface of the base plate. Also, the cone marker uses a base frame for use in the lower part of the cone marker, the base frame with rotors that is formed by including at least one rotor in at least one side surface of a rectangular frame in a plan view at the lower part of the cone marker.SELECTED DRAWING: Figure 2 |
