PROBLEM TO BE SOLVED: To provide a hollow rubber roller wheel in which a diameter of a shaft can be freely decided and a plurality of hollow rubber rollers can be connected without performing difficult work such as attaching to one shaft.SOLUTION: A hollow rubber roller 30 has a cylindrically-shaped external wall 31 and a pair of annular side-walls 32, 33 extending inwardly from the circular edge of both ends of the external wall 31. A wheel 10 attached with the hollow rubber roller includes a wheel body 11, a convex connection part 14 and a concave connection part 15. A wheel body 10 presents a pillar shape, and a pair of annular grooves 12, 13 fitted with inner circumferential edges of the pair of annular side-walls 32, 33 are formed in an outer circumferential surface. The convex connection part 14 is axially projected from one end face of the wheel body 11. The concave connection part 15 is formed in the other end face of the wheel body 11, and has a shape corresponding to the convex connection part 14. |
