A magnetic type rotation transmitting mechanism has a rotating plate made of a magnetic material, and a magnet to which the rotational movement of the rotating plate is transmitted through a magnetic coupling between the magnet and the rotating plate. When the rotating plate is rotated, a plurality of oblique edge portions formed on the outer peripheral edge of the rotating plate rotate while sequentially passing through a magnet-facing area. The oblique edge portions move in the direction of the rotation centerline of the rotating plate, the rotation centerline being perpendicular to the center axis line of the magnet. The magnet is rotated about the center axis line by a magnetic force occurring between the magnet and the oblique edge portions passing through the magnet-facing area. It is possible to realize a small and compact mechanism for extracting rotation.
