摘要： There is provided a belt conveyor for applying a tension to a belt (3) by snap rollers (8a) so as to simplify a supporting structure for the snap rollers for releasing and tensioning the belt (3) by the snap rollers (8a) without using any tools. In accordance with the invention the belt (3) is wound around the outer circumference at a lower side of a driving roller (7), the snap rollers (8a) are supported by supporting members (31), the base ends of turning arms (13) are pivotable at the end part of a supporting shaft (9), a torsion spring (12) is fitted to the end part of the supporting shaft (9), one end of the spring (12) is engaged with the supporting shaft (9), the other end of the spring (12) is engaged with the turning arm (13), the turning arm (13) is turned to cause the torsion spring (12), its reaction force causes both snap rollers (8a) to press the belt (3) against the outer circumference of the driving roller (7) to enable the driving power to be transmitted.
