ンジュバン型振動子。A pair of metal blocks consisting of a front plate and a backing plate are brought into contact with the upper and lower end surfaces of the annular piezoelectric element, which are stacked electrically in parallel and mechanically in series via an annular terminal plate, and an insulating cylinder is fitted. Insert the piezoelectric element and the metal block into one piece with a tightening bolt inserted through the center hole of the piezoelectric element and the terminal plate, and fit into the center hole of the piezoelectric element and the terminal plate. A Langevin type vibrator characterized in that the outer peripheral surface of the insulating cylinder has a cross-sectional shape other than circular to prevent rotational displacement of the piezoelectric element and the terminal plate in the radial direction during the above-mentioned fastening.
