The invention provides a rolling wheel, comprising a rolling wheel main body and an inner ring, wherein the inner diameter of the rolling wheel main body is equal to the outer diameter of the inner ring; the inner ring is arranged in the rolling wheel main body; each of the left side and the right side of the inner diameter of the rolling wheel main body is provided with threads; retainer rings are further arranged on the threads; the inner diameter of each retainer ring is smaller than that of the inner ring. The rolling wheel has the advantages and positive effects that the inner ring is arranged on the inner diameter of the rolling wheel main body, and each of the left side and the right side of the inner ring of the rolling wheel main body is provided with the retainer ring, so that the inner ring is fixed in the rolling wheel main body, therefore the movement of the rolling wheel is conveniently performed, sliding friction is changed into rolling friction, and the movement of the rolling wheel is more precise; meanwhile, rubber lining is further arranged on the outer diameter of the rolling wheel main body, so that the rolling wheel is more wearable.
