PROBLEM TO BE SOLVED: To rationally for a non-contact transmission mechanism, capable of satisfactorily transmitting rotational force from one side to the other. SOLUTION: A plurality of magnets 53 are disposed, so that their N poles and S poles appear alternately relative to the outer peripheries of a driving wheel Wa and a driven wheel Wb. An annular member 52, formed out of a magnetic substance, is provided on the inner end side (rotational center side) of the plurality of magnets 53, so that magnetic flux projects outward in the non-axial direction.
