DRIVING MECHANISM, LENS BARREL AND CAMERA

摘要

A driving mechanism includes a first piezoelectric element and a first driving member that is driven by the first piezoelectric element and that vibrates in a first direction. The first driving member includes a second piezoelectric element and a second driving member that is driven by the second piezoelectric element and that vibrates in a second direction different from the first direction. A difference between the vibration resonance frequency of the first driving member and the vibration resonance frequency of the second driving member is equal to or less than the half-width at a half maximum of a function representing an amplitude frequency characteristic in the vibration of the first driving member.
