PROBLEM TO BE SOLVED: To provide a belt meandering prevention device capable of effectively preventing the meandering of a conveying belt. SOLUTION: These belt meandering prevention devices 8a, 8b comprise roller supporting rotating bodies 18, 18b and guide roller bodies 20, 20b supported on the roller supporting rotating bodies 18, 18b. The belt meandering prevention devices 8a, 8b further comprise stopper bodies 21, 21b for positioning the guide rollers 20, 20b in the state that its rotating center axis X matches the lateral direction of the conveying belt 2 when viewed from top by engaging with the roller supporting rotating bodies 18, 18b and biasing bodies 23, 24b for biasing the roller supporting rotating bodies 18, 18b toward the stopper bodies 21, 21b. When the meandering of the conveying belt 2 occurs, the roller supporting rotating bodies 18, 18b are rotated against the biasing of the biasing bodies 23, 23b, and the guide roller bodies 20, 20b are so tilted that its rotating center axis X is tilted relative to the lateral direction of the conveying belt 2 when viewed from top.
