摘要：

PROBLEM TO BE SOLVED: To provide a spiral conveying device capable of descending an object to be conveyed from an upper side to a lower side along a truer spiral shape by its own weight and smoothly conveying the object to be conveyed from an upper conveying means to a lower conveying means without displacing it to an outer peripheral side by centrifugal force. SOLUTION: The spiral conveying device is provided with a strut 1; a circular ring member 5 coaxially arranged so as to surround the strut 1; and a plurality of cone bodies 7 formed with shaft parts 7a, 7b at both ends and radially arranged between the strut 1 and the circular ring member 5. The plurality of cone bodies 7 are arranged at positions gradually turned in a circumferential direction while gradually directed from an upper side to a lower side. The shaft part 7a at each small diameter side is supported on the strut 1 side and the shaft part 7b on a large diameter side is supported on the circular ring member 5 side rotatably around an axis of the cone body 7 respectively.
