Abstract
In order to provide an actuator having great driving force and high impact resistance, an actuator of the present invention has a driving shaftthat can be vibrated in the shaft direction by a piezoelectric deviceprovided at its one end and a moving memberthat is friction-engaged with the driving shaftand moves on the driving shaftdue to the vibration of the driving shaft. The driving shafthas two parallel shaft sliding faceson its surface. The moving memberhas two moving member sliding facesthat are in slide-contact with the shaft sliding faces. The moving memberis friction-engaged with the driving shaftsuch that the moving member sliding facesclamp the shaft sliding faces
