摘要： A head driving device includes a head supporting portion supporting a head member, a first beam, a second beam, a first piezoelectric unit including a pair of piezoelectric elements, and a second piezoelectric unit including a pair of piezoelectric elements. When voltage is applied to the piezoelectric elements of the first piezoelectric unit, the piezoelectric elements deform, and a distal end of the first beam moves. The piezoelectric elements of the second piezoelectric unit also deform by application of voltage, and moves a distal end of the second beam in a same direction as the distal end of the first beam.
