To provide a multi-angle rotary display base, capable of displaying middle to large display items such as art works, formation works, industrial products, and merchandise, or small pieces such as plastic models and figures in such a mode as to be observed and appreciated from multiple angles at a single viewpoint instead of planar rotation as in conventional rotary display bases.

The device comprises a rotary base rotatably mounted on a base plate, and a second shaft projected diagonally upward from it, provided with a first shaft rotatably engaged with it, on forward end of which a display item installation device is provided to have inclination along the length direction, and a circular gear fixed to a lower end of it to be engaged with a gear provided on a column projected from the center of the base plate. As the rotary base is rotated, the first shaft rotates to the second shaft in the circumferential direction, while generating both revolution and rotation of the display item installation device. The display item can thus be observed and appreciated from all directions including upward and downward at a single view point.
