Description

  The present invention relates to a resonator support device having a structure in which a support part of a booster is clamped so as to be sandwiched laterally by a receiving part of an arm and a stopper attached to the arm with a screw.

  The resonator support device disclosed in Patent Document 1 is a stopper for a support portion of a booster in a state where a resonator including a vibrator is supported by two arms that are opposed to each other in a lateral direction of the resonator support device. Depending on the tightening torque between the booster and the receiving part, the tightening torque between the horn and the booster, and the tightening torque between the booster and the vibrator, the stopper to the support part of the booster loosens, the vibrator breaks down, and the metal When the two are bonded, the vibration energy due to the sound wave or the ultrasonic wave may not be properly transmitted from the resonator to the plurality of metals, and thus the plurality of metals may be defectively bonded or uneven.

The resonator support device is characterized in that it is set to a value smaller than a tightening torque for tightening so as to sandwich it from both sides.   Positioning portions that are fitted to each other when connecting the horn and the booster with the stat bolt are provided at both ends of the horn in the lateral direction and an end portion of the booster located on the horn side. The resonator support device according to claim 1, which is characterized in that.
