    摘要: A driving mechanism includes a first piezoelectric element that vibrates in a thickness-shear vibration mode in a first direction, a first member that is driven to vibrate in the first direction by the first piezoelectric element, a second piezoelectric element that is supported by the first member and that vibrates in the thickness-shear vibration mode in a second direction, and a second member that is driven to vibrate in the second direction by the second piezoelectric element.
