- 摘要：
PROBLEM TO BE SOLVED: To provide a compact Langevin ultrasonic vibrator of outside clamping type wherein vibration of a piezoelectric element unit can be taken out efficiently.
SOLUTION: A through-hole 331 through which the electrode of the piezoelectric element unit 2 is taken out is formed in a lining member 33 so that the opening on the side of the abutment surface 33a thereof is formed at a position where the shortest distance of the center O of the abutment surface 33a of the lining member 33 and the opening of the through-hole 331 (the distance from the center O to the end of the opening on the center O side) is larger than 90% (0.9r) but smaller than 100% (r) of the radius of the piezoelectric element unit 2. Furthermore, the piezoelectric element unit 2 is arranged not to close the through-hole 331, and the periphery of each piezoelectric element 21 constituting the piezoelectric element unit 2 is located within 110% (1.1r) of the radius of the piezoelectric element 21 from the center of the abutment surface 33a of the lining member 33.
