Abstract:
1. A motor device comprising: a transmission substrate formed with a transmission portion that is wound around at least part of an outer periphery of a rotator, the transmission portion having a first end portion and a second end portion; and a driving substrate that has a driving portion, connected to the first and second end portions, which acts on at least one of the first and second end portions to move the transmission portion by a certain distance in a state in which the transmission portion is relatively tightly wound around at least part of the outer periphery of the rotator so that a rotational force is transmitted between the rotator and the transmission portion and return the transmission portion to a predetermined position in a state in which the transmission portion is relatively loosely wound around at least part of the outer periphery of the rotator so that the rotation force transmission state is released, and is connected to the transmission substrate so that a driving force due to the driving portion acts on the transmission portion.
