The aim of this research is to realize the micro piezoelectric actuator for a high intense magnetic field and a cryogenic environment. There is a demand for high speed rotary type actuator for analysis equipments. By using bolt clamped Langevin type transducer and a simulation about the pre-load, we have realized the drive of rotor by the piezoelectric vibrator under the cryogenic condition. We have also succeeded in driving the rotary micro piezoelectric actuator under the condition of 10K and 7T.
