成してなる、ベルト走行装置。 An endless belt is stretched between the driving roller and the driven roller, and band-shaped elastic guide members adhered to the inner periphery of both side edges of the belt are applied to both end surfaces of at least one of the rollers to tighten the belt. In a belt running device that drives the drive roller to run the belt while restricting movement in the width direction, the inner surface of the elastic guide member facing the end surface of the roller is removed from the adhesive surface of the elastic guide member. A belt running device formed in a tapered shape that separates from the roller end face as it moves away from the roller end face in the thickness direction.
