Walking doll

A walking doll comprising:

• a body;
• a power crank mechanism in the body;
• a pair of feet having the same length as each other, the feet each having upper ends extending into the body and connected to and driven by the power crank mechanism, the feet being driven in an oscillating direction in a forward and rearward manner with respect to the body, for alternately oscillating the feet back and forth by force, the feet having lower ends extending outside the body on which the body stands erect on a floor, the lower ends being fixed to and only movable with the upper ends of the feet, the lower ends of the feet each having a narrow surface in contact with the floor, each narrow surface having a curvature in said oscillating direction and being narrow transverse to said oscillating direction, both of the feet being constantly in contact with the floor when the doll is walking;
• and
• a member for adjusting a position of a gravitational center of the walking doll, the member being movably connected to the body and free of the power crank mechanism for movement, in a first plane which is parallel to the oscillating direction and also for movement in another plane which is orthogonal to the first plane, so that the member is movable for a three-dimensional shifting of position of the gravitational center, forwardly, backwardly and outwardly with respect to the body.
