ことを特徴とする駆動装置。 A piezoelectric element that generates an elongation force in the axial direction when a voltage is applied, a flight pin head that is provided in contact with the piezoelectric element and flies due to the elongation force of the piezoelectric element, and a pin that is integrated with the flight pin head. , a leaf spring that holds the flight pin head and the pin and has a biasing force to return the flight pin to its original position when the stretching force is removed; and a housing that holds the piezoelectric element and the leaf spring. A driving device characterized in that the driving device includes an elastic body that fills a space between an inner wall surface of the housing and the piezoelectric element and applies pressurization to the piezoelectric element to resist the stretching force.
