Beschreibung
Zusammenfassung:	The present invention relates to an evaluation jig for a piezoelectric element exciter and an evaluation device of a piezoelectric element exciter including the same. According to one embodiment of the present invention, a jig which is provided to fix a piezoelectric element exciter to evaluate the same is an evaluation jig for a piezoelectric element exciter, which comprises: a base band; a first support unit which is erected from the base band to be extended, and supports one side surface of the piezoelectric element exciter; a second support unit which is rotated by being hinge-coupled to the first support unit and comes in contact with the first support unit to support the other side surface of the piezoelectric element exciter; and a fixing member which fixes by pressurizing the piezoelectric element exciter in a state of being interposed between the first support unit and the second support unit. Therefore, the negative pressure evaluation of a piezoelectric element exciter may be precisely performed. 본 발명은 압전소자 익사이터의 평가용 지그와 이를 포함하는 압전소자 익사이터의 평가장치와 관련된다. 본 발명은 실시예로 압전소자 익사이터를 고정하여 평가하기 위한 지그로서, 기저대, 상기 기저대로부터 직립하여 연장되고 상기 압전소자 익사이터의 일측면을 지지하는 제1지지부, 상기 제1지지부와 힌지 결합되고 회동하여 상기 제1지지부와 맞닿음으로써 상기 압전소자 익사이터의 다른 일측면을 지지하는 제2지지부 및 상기 제1지지부와 상기 제2지지부의 사이에 개재된 상태의 상기 압전소자 익사이터를 가압하여 고정시키는 고정부재를 포함하는 압전소자 익사이터의 평가용 지그를 제시한다.
