PROBLEM TO BE SOLVED: To provide a model body drive device, drive body and model body which realize the kicking up or swinging down of leg parts of the model body being separated from the drive body with a partition. SOLUTION: In the model body driver 2, the model body 20 makes actions driven by the drive body 100 disposed below it being separated with the partition 5. The model body 20 has a plurality of leg parts each rockable longitudinally and magnets Mfl, Mfr, Mrl and Mrr are provided at respective foot end parts of the plurality of leg parts with one magnetic polarity turned onto each sole. In the drive body 100, several sets of electromagnet groups Efl, Efr, Erl and Err in which a plurality of electromagnets with the magnetic polarities of them turned vertically is arrayed in proximity in a running direction along the undersurface of a running board are provided corresponding to the respective foot end parts of the plurality of leg parts of the model body above it. The electromagnets arrayed in the several sets of electromagnet groups Efl, Efr, Erl and Err are controlled excited by a control means to make magnetic forces work on the permanent magnets Mfl, Mfr, Mrl and Mrr at the respective foot end parts of the plurality of leg parts of the model body thereby causing the plurality of leg parts to oscillate.
