A roller unit to transport an article is provided to prevent the poor quality of a transfer product by preventing a roller and an axis member being flown too much excessively. A roller unit to transport an article comprises: a frame(20) having a shaft connection hole(50) at both wall unit to be faced each other, located along the transfer direction of an article(2); a shaft member both end unit(40) of a center unit formed at the both wall unit of the frame; and a plurality of transferring rollers(30) transferring the article. The shaft connection hole is formed at the both wall unit of the frame, facing each other, along the longitudinal direction at regular interval. The distance(D) between the center units of the shaft connection hole neighboring each other is relatively small, in comparison with the diameter(d) of the transferring roller connected to the shaft connection hole while the shaft member of the center unit is inserted in.
