Abstract:
A driving apparatus has a piezoelectric element as a driver. The driving apparatus includes a first vibrator which generates an elliptical vibration when a voltage of a predetermined frequency is applied; a first member which holds the first vibrator; a second member which includes a first sliding member to which the first vibrator is pressed and makes a relative displacement with respect to the first member by being driven by the elliptical vibration of the first vibrator; and a first resonance preventive member which is provided to the second member and prevents a resonance in the second member from being generated by the elliptical vibration of the first vibrator.
