In order to provide a magnetic rotation transmitting device capable of obtaining a large transmitting torque without using a large-sized permanent magnet, in an axial-type magnetic rotation transmitting device, which includes a driving rotation body having one or plural magnetic line(s) in which plural first magnets (10A) are disposed in a circumferential direction on a first disk (11A) at almost equal intervals, a drive source rotationally driving a drive shaft of the driving rotation body, and a driven rotation body having one or plural magnet line(s) in which second magnets (20A) of the same number as the first magnets (10A) are disposed in the circumferential direction on a second disk (21A) at almost equal intervals, symmetrically disposed to, and magnetically coupled with the driving rotation body with a magnetic coupling gap and, which utilizes a magnetic operation and which allows the driven rotation body to rotate by rotationally driving the drive shaft by means of the drive source, the first magnet (10A) has a N-magnetic pole portion and a S-magnetic pole portion, and an extended surface of a boundary surface between the N-magnetic pole portion and the S-magnetic pole portion approximately overlaps with a driving center line as being a rotation center line of the driving rotation body, the second magnet (20A) has the N-magnetic pole portion and the S-magnetic pole portion, and the extended surface of the boundary surface between the N-magnetic pole portion and the S-magnetic pole portion approximately overlaps with a driven center line as being the rotation center line of the driven rotation body, adjacent and facing surfaces of the first magnets (10A) adjacent to each other on the first disk (11A) are disposed so that magnetic pole faces having the same polarity make pairs, and adjacent and facing surfaces of the second magnets (20A) adjacent to each other on the second disk (21A) are disposed so that the magnetic pole faces having the same polarity make pairs.
