Two rollers and a rotation drive means having a rotation drive motor and rotating the two rollers in the same direction and at the same circumferential speed, for supporting a sphere on either one of the two rollers. The constriction is formed, and the two axially opposing surfaces of the roller forming the constriction have a center located on the axis of the roller with the constriction and a diameter that is the same as the diameter of the roller with the constriction. A rotation drive device for a sphere that is a partial curved surface of the same sphere.
