<p>The disclosed motor device is provided with: a rotor (SF); a contact member (BT) applied to at least a portion of the outer periphery of the rotor; a drive unit (AC) that is connected to the contact member and that causes the contact member to move; an amplification mechanism (20) that amplifies and transmits to the contact member the amount of motion of the contact member that is on the basis of the amount of driving of the driving unit; and a control unit (CONT) that causes the drive unit to conduct a drive operation that, with a torque transmission state between the rotor and the contact member, causes the contact member to move a certain distance, and a return operation that, with a state that terminates the torque transmission state, returns the contact member to a predetermined position.</p> |
