Since the outer peripheral surface of the magnetic body 6 is formed into a conical arc-shaped surface that can be clamped, in addition to the clamping action of the pair of holding members 3, 3 of the clamping mechanism 4, the magnetic body 6 made of the conical annular material is formed. The road cone W can be held by the magnetic force action of the outer peripheral surface and the conical arcuate inner surfaces of the magnets 5, 5, and the holding members 3, 3 are held by the ring-shaped members and the magnets, and the conical shape. The road cone can be held by the magnetic action of the outer peripheral surface of the magnetic body made of a ring material and the conical arc surface of the inner surface of the magnet, and the delivery position T of the delivery section C and the installation and collection on the road surface G.

Further, in this case, since the traveling speed _HV of the moving vehicle A and the turning speed _RV of the turning member 1 are set to be substantially the same speed in opposite directions, the road cone W acting as the moving vehicle A moves is also set. It is possible to further suppress the lodging of the road cone W due to the inertial force of , and it is possible to perform stable installation work.

In this case, as shown in FIG. 11, the reciprocating turning mechanism 2 is such that when the road cone W is collected, the traveling direction P of the moving vehicle A is opposite to the traveling direction H when the road cone W is installed. , and the traveling direction P of the moving vehicle A and the upward turning direction S from the installation/recovery position SK to the delivery position T are opposite to each other. When the road cone W is stopped at the installation recovery position SK and approaches the turning member 1, the clamping mechanism 4 clamps the road cone W, and the turning member 1 turns upward from the installation recovery position SK to the delivery position T and moves. The traveling direction P of the vehicle A and the upward turning direction S from the installation/recovery position SK to the delivery position T are opposite to each other, so that sliding between the road cone W and the road surface G can be suppressed. can be collected smoothly.

Further, in this case, the turning transfer mechanism D is disposed on each of the left and right sides of the moving vehicle A, and the pair of turning transfer mechanisms D and D on the left and right sides are formed in a bilaterally symmetrical structure. When the road cone W is installed and collected on the road surface G at the boundary between the driving lane and the overtaking lane during the traffic lane regulation on the expressway, the other turning transfer mechanism D on the right side in the traveling direction is used.
