Abstract: Disclosed herein is a roller unit for a drawer capable of decreasing the number of components, improving assembly productivity, and continuously maintaining a normal assembly state of the component by changing a structure of an assembled portion of the components configuring the roller unit. The roller unit includes a rotating support shaft fixed to an accommodation body, an idle roller idle-rotatably coupled to the rotating support shaft, and coupling structures provided at assembled portions of the rotating support shaft and the idle roller, respectively, the coupling structures including a locking groove formed in a circumferential direction with respect to an outer circumferential surface of the rotating support shaft, a protrusion formed on an inner circumferential surface of a fastening hole of the idle roller and coupled to the locking groove, and an assembly guiding groove formed at one end of the outer circumferential surface of the rotating support shaft.
