PROBLEM TO BE SOLVED: To provide a meandering prevention device in a double-belt conveyor capable of exhibiting a higher meandering prevention effect. SOLUTION: The double-belt conveyor is arranged such that it circulates a space from a vertical boom 4 of a continuous unloader to a horizontal boom 3. Two meandering prevention mechanisms 31, 32 are arranged on the vertical boom 4 and wide rolls 25, 26 for supporting belts 10b, 11b at a return side to the flat state are provided between the two meandering prevention mechanisms 31, 32. The respective meandering prevention mechanisms 31, 32 are constituted of an inclination roll 34 for obliquely inclining both ends of the return side belt against a center part.
