PROBLEM TO BE SOLVED: To provide a rotation transmission device, including a self-adjustable slip function which applies a large slip ratio when a rotation angle speed ratio of input and output is almost infinite, and reduces the slip ratio automatically as the rotational speed of an output device is increased and the rotation angular speed ratio is reduced. SOLUTION: This rotation transmission device is provided with a drive disc and a driven disc, and is formed so that magnetic force may act between both discs, by attaching a permanent magnet to the drive disc and using a member formed out of a ferromagnetic body on at least one part of the driven disc. Both discs are disposed, so that the central axis of both the discs is included in a common plane, and a tangent for the drive disc orthogonal to the plane and a tangent orthogonal to the plane at a desired position on the radius of the driven disc is opposed, in parallel with each other at a prescribed proximity distance, so that rotational movement transmitted to the drive disc from the outside through the central axis is transmitted to the driven disc by action of the magnet force, and the rotational movement of the driven disc is transmitted to the outside via the central axis.
