A conveying device for conveying a conveyance target member to be conveyed, comprising: a rotary shaft; a plurality of holding mechanisms attached to the rotary shaft in a manner rotatable in response to rotation of the rotary shaft and each capable of holding the conveyance target member, wherein the plurality of holding mechanisms are arranged along a circumference of the rotary shaft at respective positions having different angles about the rotary shaft; a speed-changing mechanism which changes an angular speed of each of the plurality of holding mechanisms such that an angular difference arises between mutually adjacent two of the plurality of holding mechanisms; a first cover attached to a first holding mechanism which is one of the adjacent two holding mechanisms, such that the first cover covers a circumferential gap between the adjacent two holding mechanisms from an outside thereof in a radial direction of the rotating shaft, the first cover moving in a first circumferential direction together with the first holding mechanism; and a second cover attached to a second holding mechanism which is the other one of the adjacent two holding mechanisms, such that the second cover covers the circumferential gap from the outside thereof in the radial direction, the second cover overlapping with the first cover in the radial direction and moving in a second circumferential direction together with the second holding mechanism relative to the first cover moving in the first circumferential direction together with the first holding mechanism, wherein the first cover and the second cover have respective lengths which are long enough such that the first and second covers are able to overlap with each other in the radial direction, in a state in which the adjacent two holding mechanisms are furthest apart from each other.
