This curved belt conveyor device is configured from tapered rollers in which a restraining pulley (21) has the same angle as the taper angle of a head pulley (17), and the length in the rotational axis direction of a tapered outer tube is set shorter than the length in the rotational axis direction of the tapered outer tube of the head pulley (16), and the restraining pulley (21) is disposed in the state of the large-diameter side end of the tapered outer tube being positioned at the vicinity of the outer peripheral edge of a fan-shaped belt and the peripheral surface of the tapered outer tube being tilted in a manner such that the portion close to the outer periphery having the length from the pivot to the outer peripheral edge of the fan-shaped belt (15) entrained around the head pulley presses towards the peripheral surface of the tapered outer tube of the head pulley (17). |
