PURPOSE:To operate a device with low oscillation and low noise, by transmitting the rotational force of a driving wheel to a driven wheel, with the mutual attractions of permanent magnets fitted respectively on the outer peripheries of the driving wheel and the driven wheel. CONSTITUTION:On a driving shaft 1, a driving wheel 2 is integrally fitted, and at a position with a specified distance from the driving shaft 1, a driven shaft 3 in parallel with the driving shaft 1 is rotatably supported via a bearing. On the driven shaft 3, a driven wheel 4 is integrally fitted in a state separated properly from the driving wheel 2, at a position confronted with the driving wheel 2. On the respective outer peripheral surfaces of both the wheels 2, 4, the permanent magnets 6, 7 of different poles consisting of mutually attracted poles N, S are fitted at the same pitch. As a result, a rotational force can be transmitted to the driven shaft 3 from the driving shaft 1.
