ABSTRACT:
An actuator includes an electromagnetostrictive element that has one end located on a front side and the other end located on a rear side. An output shaft penetrates the electromagnetostrictive element and is pressurized toward the rear side of the electromagnetostrictive element. A housing houses therein the electromagnetostrictive element and the output shaft, and bearing portions respectively support the front side and the rear side of the output shaft. A bias spring is provided between the rear side of the output shaft and the housing, and a displacement sensor detects a position in an axial direction of the shaft.
