A hollow caster structure includes a base, a caster body pivotally connected with the base, a first wheel unit mounted on the caster body, and a second wheel unit mounted on the caster body. Each of the first wheel unit and the second wheel unit forms a viewing space. Thus, the viewing space of each of the first wheel unit and the second wheel unit provides a visible effect. In addition, the hollow caster structure has a lighter weight by provision of the viewing space. Further, the parts of the hollow caster structure have different colors which are visible from the viewing space.
