PROBLEM TO BE SOLVED: To provide a belt-driven roller conveyor with an easy maintenance capable of prolonging a service life of the belt by using a magnetic substance belt and driving a conveying roller without applying a tension to the belt in the state of being adsorbed to a roller made of permanent magnet. SOLUTION: The roller 3a made of permanent magnet is fixed to one end of shafts 13 of a large number of conveying rollers provided between frames 2, 2 in parallel and a ferromagnetic substance endless belt 5 in the absorbed stated is arranged at a lower part of this roller 3a row. An interlocking roller 6 having a large friction resistance is provided below a space between a shaft driven by the ferromagnetic substance belt and a not driven shaft against the conveying roller in a range not applied to the ferromagnetic substance belt 5 at a head and a tail part of the conveyor. All conveying rollers are driven to convey articles by pressing this interlocking rollers to the conveying roller 3 by a spring 11 to interlock it.
