PROBLEM TO BE SOLVED: To provide a suspension type rotating mirror whose set place is easily changed, while maintenance work for a power source is made free. SOLUTION: A motor 3 is attached to the lower end of a supporting rod 1 hanging in an up-and-down direction so that a motor driving shaft 7 may turn downward, and the motor 3 is surrounded outwardly by a three-dimensional mirror 2 obtained by assembling at least two convex mirrors 2a in a three- dimensional and hollow state. The lower end of the mirror 2 is supported to be integrally rotated at a shaft end extended from the shaft 7, and the upper end of the mirror 2 is supported to be freely rotate around the rod 1. Furthermore, an electric lead wire 10 extended from the motor 3 is made to pass through the inside of the rod 1 and is extended to the outside of the mirror 2, then a solar battery 4 is connected to the extended end. |
