PROBLEM TO BE SOLVED: To provide a rocking assembly having simple structure and low height and is possible to be driven by a little power. SOLUTION: This rocking assembly comprises a rocking driver 14 hung by hangers 23 from stanchions 22 installed on a base 12. The rocking driver 14 then is independently driven back-and-forth and right-and-left by two servomotors. Thus, the rocking driver 14 can shift to optional directions within a substantially horizontal plane.
