A roller conveyor composed of a main body, several rollers, a roller's fixed block and a transmission device and is shaped as a rectangle or a circular arc. The two sides of the main body are preferably composed of an aluminum extrusion frame. The roller is fixed on the aluminum extrusion frame at the two sides of the main body by coupling with a pair of roller's fixed blocks, one being connected to a concave trough positioned on each side of the main body. The inner part of the roller includes a bearing stand of cup shape, a central shaft, an end cover, and a bearing of industrial use. On the outer surface, there is a concave trough for connection with a PU belt and a transmission device to turn and power the rollers. Also, another embodiment of the invention employs a leaning cone roller-type conveyor to make the roller comply with the circular arc shape and enable the conveyor to make a turn.
