摘要:
A driving apparatus that improves the precision of driving control for a driven member by reliably ensuring the desired motion of the tip member. Regulating members, which hold a piezoelectric actuator at positions opposite a rotor R, are located at positions separated from the piezoelectric actuator by a distance L that equals or exceeds the amplitude of the oscillation generated in the piezoelectric actuator.
