PROBLEM TO BE SOLVED: To provide a commodity conveying device which can suppress the occurrence of positional deviation and rattling of a driven sprocket. SOLUTION: Because a circular part 21c is provided on a portion, facing the outer face of an auxiliary left side plate 17 of the driven sprocket 21, and the driven sprocket 21 is attached to the left side of a front shaft 23, so that the circular part 21c thereof makes contact with the outer face of the auxiliary left side plate 17; when a drive sprocket 20 is rotated with a motor 19 to convey its turning force, via a drive chain 22, to the driven sprocket 21, even if a force likely to incline the driven sprocket 21 is exerted thereon, the effect of the force is less likely to cause positional deviations or rattlings of the driven sprocket 21.
