A conveyor is provided with a casing (2), an endless conveyor belt (9) located in the casing (2) to circulate. The conveyor belt (9) has a pair of roller chains (11) attached to the peripheral edges on each side of the belt. Each roller chain (11) has a plurality of rollers (13). The casing (2) is provided with a lower split body (14) and an upper split body (15) fixed on the lower split body (14). The lower split body (14) has a pair of side frame members (17 and 18) formed by press molding. The side frames (17 and 18) each have a lower supporting portion (20) and an upper supporting portion (22), for supporting the rollers (13). That is, some portions of the casing (2) serve as the roller supporting portions (20,22). This reduces the number of steps in the manufacture of conveyors, facilitates manufacture of the same, and reduces the manufacturers' cost.
