Abstract
An actuator of the present invention comprises a piezoelectric element, one end face of the piezoelectric element in a displacement direction being supported by a fixing member, a block shaped driving member attached to the other end face of the piezoelectric element in the displacement direction, and a driven member frictionally engaged with at least one end face of the driving member in a direction orthogonal to the displacement direction, the driven member being extended along the displacement direction.
