1. a drive unit, this drive unit has the piezoelectrics as actuator, it is characterized in that, and described drive unit has:

  • The first oscillator, it produces elliptical vibration by being applied in predetermined periodic voltage;

    The first component that keeps described the first oscillator;

    Second component, it comprises the first slide unit of pressing described the first oscillator, by the elliptical vibration of described the first oscillator, is driven and is relatively moved with respect to described first component, this second component is members of frame;

    AndThe first resonance peventing member, it is located on described second component, prevents the resonance by the described second component of the generation of vibration of described the first oscillator.
