ABSTRACT:
A warning device, especially suitable for road-side use, comprises a rotor arranged to rotate about a substantially vertical axis, the rotor including three equi-angularly spaced apart cups arranged to drive the rotor in response to wind. Each cup is typically approximately hemispherical, and contains a respective outwardly facing reflector which is snap-fitted into a circumferential groove or the like in its inside surface. Each cup also has a further reflector fitted in its base, facing the opposite way to the main reflector, the backs of both reflectors being effectively sealed by the way they are fitted to the cup. The rotor is rotatably supported on a single ball bearing disposed between a downwardly facing flat surface within a recess in the rotor and the flat top of an upwardly extending stationary stub shaft.
