A motor device includes a base portion; a transmission portion that is formed with the base portion as one member and is wound around at least a part of an outer periphery of a rotator; and a driving portion which is supported by the base portion, moves the transmission portion by a certain distance in a state in which a rotational force is transmitted between the rotator and the transmission portion, and returns the transmission portion to a predetermined position in a state in which the rotation force transmission state is released.
