PROBLEM TO BE SOLVED: To provide a designed object swinging device that swings designed objects for advertisement different in size, shape and weight, under proper conditions using a single swinging device for driving.SOLUTION: The device includes: a primary pendulum 2 to be driven by a swinging device 1b bonded to an advertising body 1a; and the advertising body 1a supporting sub-pendulums 3, 4. The device also includes: a self-oscillation circuit 40 for exciting a drive coil 16 arranged in the swinging device 1b to face a magnet 17 arranged in the primary pendulum 2, to a magnetic pole repulsed or absorbed with a magnetic pole of a magnet 17 facing thereto; a DC power supply for supplying power to the circuit; connectors 8, 9 for connecting between the primary pendulum 2 and the sub-pendulum 3, 4; and a link mechanism for swinging the sub-pendulum 3, 4 along with the swinging of the primary pendulum 2. The link mechanism includes first connector connecting holes 32a, 32b arranged in the periphery of a primary pendulum support shaft 2a and a second connector connecting holes 33a, 33b arranged in the periphery of sub-pendulum support shafts 11, 12. The first connector connecting holes 32a, 32b and the second connector connecting holes 33a, 33b are connected with the connectors 8, 9. |
