A roller structure and a manufacturing method thereof are introduced. The roller structure includes a roller rotatable about an axial portion, an end of a bush is fixed to an end of the axial portion, and another end of the bush having an engaging portion coupled to a load, a first stop portion disposed at another end of the axial portion and the bush has a second stop portion positioned opposite to the first stop portion such that the roller rotates between the first stop portion and the second stop portion; wherein the engaging portion of the bush has a feeding space that receives a material of the load to couple the engaging portion to the load. Hence, the roller structure and the manufacturing method thereof provide a modularized roller structure for carrying a load, effectuate modularized assembly and production, enhance assembly efficiency, attain structural streamlining, and cut costs.
