Abstract
An actuator comprises: an electro-mechanical conversion element; a driving frictional member that is mounted onto one side in an extension/contraction direction of the electro-mechanical conversion element; a driven member that is frictionally engaged with the driving frictional member; a fixed frame; an elastic supporting member that is mounted onto the other side in the extension/contraction direction of the electro-mechanical conversion element and displaceably supports the other side of the electro-mechanical conversion element with respect to the fixed frame; and a pressing member that presses the elastic supporting member in the extension/contraction direction to maintain the elastic supporting member in an elastically deformed state.
