Drive for a crystal ball for moving a figure upwardly and downwardly
 The present invention provides a crystal ball which move upwardly and downwardly, wherein the convex surface of the planetary gears which is used to drive the revolving disk is a bevel to form a bulgy state, and a mantle surrounding said bulgy convex surface is on the upper side of the revolving disk; and the dynamic phenomena including revolution, rotation and moving upwardly and downwardly performed by the doll inserted into said mantle are driven by the rotation of the revolving disk and the planetary gears.
