Abstract
A rotary displacement structure of a fun device includes a container body. The container body has a space therein. A fluid is provided in the space. A rotary displacement unit is disposed in the space. The rotary displacement unit has buoyancy or gravity. The rotary displacement unit includes at least one blade assembly. When the container body is overturned, the rotary displacement unit will rise or descend through buoyancy or gravity. At the same time, the blade assembly enables the rotary displacement unit to rotate when ascending or descending, so as to obtain a different visual effect from the prior art.
