PROBLEM TO BE SOLVED: To provide a spiral endless conveyor device which does not increase the installation area or require any complicated device for the elevating/lowering operation by preventing the diameter of a driving drum from increasing in comparison with the width of a conveyor. SOLUTION: The spiral endless conveyor device A capable of performing the forward/reverse operation comprises a driving drum 1 rotatable around the axis, an endless conveyor 2 which is spirally provided around the driving drum 1 and formed by combining hard synthetic resin parts, a hard synthetic resin conveyor rail 3 to be slidably engaged with both sides of the endless conveyor 2, a supporting body 4 for supporting the conveyor rail 3, an outer frame 5 for supporting the supporting body 4, a driving drum driving device 6, and a conveyor initial driving device provided on any one of upper and lower parts.
