To provide a disk type magnetic coupling which can prevent adhesion or collision of the magnetic poles of two magnetic disks by a simple work with a light force and can align the central axis of rotation easily, and to provide its assembling method and a jig for assembling a disk type magnetic coupling.
In a disk type magnetic coupling 200 performing noncontact transmission of rotation by facing two magnetic disks 210 and 220 at an interval while arranging magnetic poles 213 and 223 alternately on the disk surface, the magnetic disk 210 is secured to an assembling nut 110 screwed over an assembling bolt 120, distal end 121 of the assembling bolt 120 is made to abut on a reference surface on the opposite side and turned to advance up to a fixed position on the side of an opposing magnetic disk 220.
