Abstract
Complicated movements of a walking doll such as going frontward or backward while making a big turn or making a turn in place is possible if the walking doll includes a body with a gear unit for supporting and driving a pair of feet having the same length and moved in an oscillating manner in the front/rear direction with respect to the body without restraint. The doll stands erect on the feet since they have surfaces which stay in contact with the floor. These surfaces have a curvature in the oscillating direction and the curvature is constantly in contact with the floor. A member for adjusting the position of a gravitational center of the doll is swiveled or deformed on a first plane parallel to the oscillation direction and another plane orthogonal to the first plane. This can three-dimensionally shift the center of gravity frontward or backward or to a side region of the doll.
