Kind Code:

Abstract:
The present invention relates to a universal caster. The universal caster includes: a main roller body disposed at the middle portion thereof; a plurality of auxiliary rollers rotatably coupled at a predetermined distance along the circumference of the main roller body; a plurality of single casters including fixing pins for coupling the auxiliary rollers along the circumference of the main roller body; and a caster-coupling hole passing through and inserted into the roller body of the plurality of single casters so as to couple the plurality of separated single casters thereto. Thus, the plurality of single casters may be simply coupled using the separate caster-coupling hole. Also, each of the components may be simplified in structure to enable the easy manufacture of the universal caster, and the functionality and lifespan of the universal caster may be improved due to the strong coupling force between the components.
