Abstract
A piezoelectric actuator has a housing having a top portion with an opening. A Y-shaped member comprising a bottom arm and divided two top arms. The bottom arm is fixed on a bottom portion of the housing and the divided two top arms are placed in a movable state. A detachable member is so fitted into the opening of the housing as to be detachable from the opening of the housing. A piezoelectric device has one end being fixed to the detachable member and the opposite end being in contact with a valley portion of the Y-shaped member so that when the piezoelectric device extends in a longitudinal direction by a voltage application then the opposite end presses down the alley portion thereby a distance between the tops of the divided two top arms of the Y-shaped member is enlarged. A beam has opposite ends being fixed to topes of the divided top arms and a center portion displaceable in a vertical direction when a distance between the tops of the divided top arms of the Y-shaped member is changed.
