ABSTRACT:
A displacement transmitting apparatus comprising a shaft hole which throttles by piezoelectric effect, and a shaft slidably inserted into the shaft hole engaged with a driving means which advances steppingly by mechanically amplified piezoelectric effect. On-off controlling of electric voltage for the displacement transmitting apparatus and the driving means causes the shaft to advance or conversely causes the driving means to advance where the shaft is fixed.
