Abstract
An electrostatic micro-motor apparatus capable of transmitting a driving force of an electrostatic micro-motor comprises a rotor which has the shape of a gear substantially. A plurality of electrodes are disposed at a predetermined circumferential region around the rotor so as to confront the teeth of the rotor, and such that a circumferential gap is defined at the remaining circumferential region around the rotor. A transmission gear is provided in the circumferential gap so as to be brought into engagement with the rotor.
