<p>PURPOSE:To make it possible to easily drive an output lever by making a clutch plate absorb a rotor at current supply to a clutch coil, and by actuating an external force as the clutch plate is separated from the rotor at no current supply. CONSTITUTION:A clutch plate 17 is adsorbed to a rotor 12, by supplying an electric current to a clutch coil 13 from the outside through a sliding element 16 and a slip ring 14. Hereafter, the current is supplied to a piezoelectric ceramics 1, vibration is generated, the vibration is amplified with a stator 2, and the rotor 12 is rotated through a lining plate 4. Rotating force of the rotor 12 is transmitted to the rack part of an output lever 8 through a pinion 18, and the output lever 8 is moved rectilinearly. Further when a current is not supplied to the clutch coil 13, the rotating force of the rotor 12 is not transmitted as the clutch plate 17 is not adsorbed to the rotor 12. Consequently, when the output lever 8 is moved by external force, the force is sufficient only to rotate the clutch plate 17, as pressing force from a pressing mechanism 7 does not influence the motion.</p> |
