Abstract
A power transmission apparatus includes a first pulley and a second pulley. A belt is extended around them. A supply unit supplies a voltage such that the first pulley and the belt are electrostatically attracted and that the second pulley and the belt are electrostatically attracted. The belt includes a conductor layer. At least one pulley includes a first electrode to which a first voltage is applied and a second electrode that is insulated from the first electrode and to which a second voltage is applied. An insulating layer or a dielectric layer is arranged between the conductor layer of the belt and the first electrode of the at least one pulley and an insulating layer or a dielectric layer is arranged between the conductor layer of the belt and the second electrode of the at least one pulley.
