A driving device comprises: an electro-mechanical conversion element enabled to expand and contract in response to input of an electrical signal; a pair of clamping members that come closer to and move away from each other with expansion and contraction of the electro-mechanical conversion element; a moving member disposed between said pair of clamping members; and flagellar members which are provided between the moving member and each of said pair of clamping members to be inclined to a direction in which said pair of clamping members come closer to and move away from each other, and which are adapted to swing when said pair of clamping members come closer to and move away from each other, to cause the moving member to move in a constant direction.
