PROBLEM TO BE SOLVED: To provide a low-cost reverse conveyance prevention mechanism for a conveyor device, preventing reverse conveyance of a conveyed object without projecting a projecting members or the like over a conveying line. SOLUTION: This reverse conveyance prevention device for the conveyor device (e.g. a roller conveyor 1) conveying the conveyed object by rotation of rollers 2 has one-way clutches 5 below the conveying line 4 for conveying the conveyed object such that the clutches 5 abut on the rollers 2. The one-way clutch 5 can idle to the direction to which the roller 2 conveys the conveyed object, and does not rotate the opposite direction to the direction allowing the idling. The one-way clutch 5 is formed around the other end of an eccentric shaft 7 having one end that is rotatably fixed, while the periphery of the clutch 5 has a friction ring 6 to restrain the roller 2.
