PROBLEM TO BE SOLVED: To facilitate the assembling work of a conveyor by providing a bearing part to be fitted to a roller shaft for pivotally supporting a roller and a guide part provided with a flat guide surface projected to the peripheral part from the bearing part and directed toward the roller. SOLUTION: Each roller shaft 31 is positioned at both ends of a roller 33, and a conveyor guide 41 is installed in the roller shaft 31. Each conveyor guide 41 of the resin is integrally formed into a disc (flange) shape, and provided with an enlarged diameter part 32 of the roller shaft 31 and the bearing part 42 to be fitted near the enlarged diameter part 32 freely to be slid, namely, freely to be rotated, and a guide part 44 projected like a disc from the bearing part 42 to the peripheral part. The inner surface of the guide part 44 is formed into a smooth and flat guide surface 45 projected toward a side of a carrying surface 11 for positioning. Furthermore, the conveyor guide 41 is fitted to the roller shaft 31 freely to be turned so as to be supported freely to be rotated in relation to a roller main body 34.
