To suppress such a failure that the shift of a moving object is hindered in a desired condition due to the arrangement error of a piezoelectric element and/or a driving shaft.
The driving device includes: a connecting body where the piezoelectric element 42 and a transmission shaft 44 are connected together; a link member 45 with which the transmission shaft 44 is frictional-engaged in a state where the link member can slide along the longitudinal direction of the transmission shaft 44; a fixing-side member which fixedly supports the link member 45; and the moving object which is fixed to the connecting body. The moving object shifts together with the connecting body with respect to the fixing-side member in accordance with the drive of the piezoelectric element 42.
