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. ## Claims ### Claim 1 A roller structure, comprising: 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; and 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, the feeding space receives a material of the load to couple the engaging portion to the load. ### Claim 2 (depends on 1) The roller structure of claim 1, wherein the bush is formed integrally with or coupled to the axial portion. ### Claim 3 (depends on 2) The roller structure of claim 2, wherein the first stop portion is formed integrally with or coupled to the axial portion. ### Claim 4 (depends on 1) The roller structure of claim 1, wherein the first stop portion is in form of a stop component fitted around the axial portion, and the axial portion has a third stop portion for limiting movement of the stop component. ### Claim 5 (depends on 4) The roller structure of claim 4, wherein a receiving chamber is concentric with the axial portion and is adapted to receive one of the first stop portion and the third stop portion. ### Claim 6 (depends on 1) The roller structure of claim 1, further comprising a connection component coupled to the axial portion, wherein the first stop portion is in form of a stop component whose movement is limited by the connection component. ### Claim 7 (depends on 6) The roller structure of claim 6, wherein the stop component is in form of a hollow-core component penetrable by the connection component. ### Claim 8 (depends on 1) The roller structure of claim 1, wherein the first stop portion penetrates the axial portion, or the first stop portion penetrates the axial portion and the bush, or the axial portion penetrates the first stop portion. ### Claim 9 (depends on 8) The roller structure of claim 8, wherein the first stop portion penetrates the axial portion and is coupled to the axial portion by a riveting mechanism, an expansion mechanism, a welding mechanism, an engaging mechanism, a fastening mechanism, an adhesion mechanism or a magnetic attraction mechanism, or the first stop portion penetrates the axial portion and the bush and is coupled to the bush by a riveting mechanism, an expansion mechanism, a welding mechanism, an engaging mechanism, a fastening mechanism, an adhesion mechanism or a magnetic attraction mechanism. ### Claim 10 (depends on 1) The roller structure of claim 1, wherein a limiting portion extends from the roller and is disposed on a surface of the first stop portion such that the first stop portion is confined to between the limiting portion and the roller. ### Claim 11 (depends on 1) The roller structure of claim 1, wherein the roller comprises one of an inner ring, a rolling component and a sliding component for fitting around the axial portion. ### Claim 12 (depends on 1) The roller structure of claim 1, wherein the engaging portion of the bush is positioned proximate to a side of the load such that the bush and the load are coupled together by a connection component. ### Claim 13 (depends on 1) The roller structure of claim 1, further comprising a frame which the engaging portion of the bush and the load are coupled to. ### Claim 14 (depends on 1) The roller structure of claim 1, wherein a diameter of the engaging portion is larger or smaller than a diameter of the roller. ### Claim 15 (depends on 1) A manufacturing method of the roller structure of claim 1, comprising a step of forming the second stop portion positioned proximate to a side of the roller by using a die in performing a pressing process on a pressed portion at another end of the axial portion.
