Abstract
In a displacement amplification mechanism for a piezoelectric element comprising a pair of lever arms for transmitting and amplifying the displacement of the piezoelectric element, and a bridge-shaped beam member held at ends of the lever arms with rivets and working as a further means for amplifying the displacement of the piezoelectric element, a semi-elliptical rib is formed in a central flat portion of the beam member to thereby increse the rigidity in the central flat portion.
