PROBLEM TO BE SOLVED: To provide a conveying device free of dust generation resulting from friction and wear of gears as a power transmitting means to rollers. SOLUTION: The conveying device is equipped with a power transmitting means 10 to transmit rotation to a pair of rollers 31 and 32, whereby an object is conveyed by rotating the rollers while the object 50 is pinched by the rollers. The power transmitting means 10 is equipped with a disk 11 rotated by a drive source 1 round the axis and having a first magnetic surface 17 furnished at the end face with permanent magnets 15 in such a fashion that N-poles and S-poles are alternately arranged radially and a pair of cylinders 21 and 22 coupled with the respective rollers and having a second magnetic surface 29 furnished at the periphery with permanent magnets 27 in such a fashion that N-poles and S-poles are alternately arranged spirally, wherein the pair of cylinders is arranged so that a prescribed gap is reserved with respect to the disk and the second magnetic surface confronts the first magnetic surface, and through the use of magnetic attracting and repelling forces, the power is transmitted from the disk 11 to the cylinders 21 and 22.
